8 <title>Release Date</title>

13 This release contains a variety of fixes from 9.4.11.
14 For information about new features in the 9.4 major release, see
15 <xref linkend="release-9-4">.
19 <title>Migration to Version 9.4.12</title>
22 A dump/restore is not required for those running 9.4.X.
26 However, if you are using third-party replication tools that depend
27 on <quote>logical decoding</>, see the first changelog entry below.
31 Also, if you are upgrading from a version earlier than 9.4.11,
32 see <xref linkend="release-9-4-11">.
37 <title>Changes</title>
43 Fix possibly-invalid initial snapshot during logical decoding
44 (Petr Jelinek, Andres Freund)
48 The initial snapshot created for a logical decoding replication slot
49 was potentially incorrect. This could cause third-party tools that
50 use logical decoding to copy incomplete/inconsistent initial data.
51 This was more likely to happen if the source server was busy at the
52 time of slot creation, or if another logical slot already existed.
56 If you are using a replication tool that depends on logical decoding,
57 and it should have copied a nonempty data set at the start of
58 replication, it is advisable to recreate the replica after
59 installing this update, or to verify its contents against the source
66 Fix possible corruption of <quote>init forks</> of unlogged indexes
67 (Robert Haas, Michael Paquier)
71 This could result in an unlogged index being set to an invalid state
72 after a crash and restart. Such a problem would persist until the
73 index was dropped and rebuilt.
79 Fix incorrect reconstruction of <structname>pg_subtrans</> entries
80 when a standby server replays a prepared but uncommitted two-phase
81 transaction (Tom Lane)
85 In most cases this turned out to have no visible ill effects, but in
86 corner cases it could result in circular references
87 in <structname>pg_subtrans</>, potentially causing infinite loops
88 in queries that examine rows modified by the two-phase transaction.
94 Avoid possible crash in <application>walsender</> due to failure
95 to initialize a string buffer (Stas Kelvich, Fujii Masao)
101 Fix postmaster's handling of <function>fork()</> failure for a
102 background worker process (Tom Lane)
106 Previously, the postmaster updated portions of its state as though
107 the process had been launched successfully, resulting in subsequent
114 Ensure parsing of queries in extension scripts sees the results of
115 immediately-preceding DDL (Julien Rouhaud, Tom Lane)
119 Due to lack of a cache flush step between commands in an extension
120 script file, non-utility queries might not see the effects of an
121 immediately preceding catalog change, such as <command>ALTER TABLE
128 Skip tablespace privilege checks when <command>ALTER TABLE ... ALTER
129 COLUMN TYPE</> rebuilds an existing index (Noah Misch)
133 The command failed if the calling user did not currently have
134 <literal>CREATE</> privilege for the tablespace containing the index.
135 That behavior seems unhelpful, so skip the check, allowing the
136 index to be rebuilt where it is.
142 Fix <command>ALTER TABLE ... VALIDATE CONSTRAINT</> to not recurse
143 to child tables when the constraint is marked <literal>NO INHERIT</>
148 This fix prevents unwanted <quote>constraint does not exist</> failures
149 when no matching constraint is present in the child tables.
155 Fix <command>VACUUM</> to account properly for pages that could not
156 be scanned due to conflicting page pins (Andrew Gierth)
160 This tended to lead to underestimation of the number of tuples in
161 the table. In the worst case of a small heavily-contended
162 table, <command>VACUUM</> could incorrectly report that the table
163 contained no tuples, leading to very bad planning choices.
169 Ensure that bulk-tuple-transfer loops within a hash join are
170 interruptible by query cancel requests (Tom Lane, Thomas Munro)
176 Fix integer-overflow problems in <type>interval</> comparison (Kyotaro
181 The comparison operators for type <type>interval</> could yield wrong
182 answers for intervals larger than about 296000 years. Indexes on
183 columns containing such large values should be reindexed, since they
190 Fix <function>cursor_to_xml()</> to produce valid output
191 with <replaceable>tableforest</> = false
192 (Thomas Munro, Peter Eisentraut)
196 Previously it failed to produce a wrapping <literal><table></>
203 Fix roundoff problems in <function>float8_timestamptz()</>
204 and <function>make_interval()</> (Tom Lane)
208 These functions truncated, rather than rounded, when converting a
209 floating-point value to integer microseconds; that could cause
210 unexpectedly off-by-one results.
216 Improve performance of <structname>pg_timezone_names</> view
217 (Tom Lane, David Rowley)
223 Reduce memory management overhead for contexts containing many large
230 Fix sloppy handling of corner-case errors from <function>lseek()</>
231 and <function>close()</> (Tom Lane)
235 Neither of these system calls are likely to fail in typical situations,
236 but if they did, <filename>fd.c</> could get quite confused.
242 Fix incorrect check for whether postmaster is running as a Windows
243 service (Michael Paquier)
247 This could result in attempting to write to the event log when that
248 isn't accessible, so that no logging happens at all.
254 Fix <application>ecpg</> to support <command>COMMIT PREPARED</>
255 and <command>ROLLBACK PREPARED</> (Masahiko Sawada)
261 Fix a double-free error when processing dollar-quoted string literals
262 in <application>ecpg</> (Michael Meskes)
268 In <application>pg_dump</>, fix incorrect schema and owner marking for
269 comments and security labels of some types of database objects
270 (Giuseppe Broccolo, Tom Lane)
274 In simple cases this caused no ill effects; but for example, a
275 schema-selective restore might omit comments it should include, because
276 they were not marked as belonging to the schema of their associated
283 Avoid emitting an invalid list file in <literal>pg_restore -l</>
284 when SQL object names contain newlines (Tom Lane)
288 Replace newlines by spaces, which is sufficient to make the output
289 valid for <literal>pg_restore -L</>'s purposes.
295 Fix <application>pg_upgrade</> to transfer comments and security labels
296 attached to <quote>large objects</> (blobs) (Stephen Frost)
300 Previously, blobs were correctly transferred to the new database, but
301 any comments or security labels attached to them were lost.
307 Improve error handling
308 in <filename>contrib/adminpack</>'s <function>pg_file_write()</>
309 function (Noah Misch)
313 Notably, it failed to detect errors reported
314 by <function>fclose()</>.
320 In <filename>contrib/dblink</>, avoid leaking the previous unnamed
321 connection when establishing a new unnamed connection (Joe Conway)
327 Fix <filename>contrib/pg_trgm</>'s extraction of trigrams from regular
328 expressions (Tom Lane)
332 In some cases it would produce a broken data structure that could never
333 match anything, leading to GIN or GiST indexscans that use a trigram
334 index not finding any matches to the regular expression.
340 In <filename>contrib/postgres_fdw</>,
341 transmit query cancellation requests to the remote server
342 (Michael Paquier, Etsuro Fujita)
346 Previously, a local query cancellation request did not cause an
347 already-sent remote query to terminate early. This is a back-patch
348 of work originally done for 9.6.

362 Support OpenSSL 1.1.0 (Heikki Linnakangas, Andreas Karlsson, Tom Lane)
366 This is a back-patch of work previously done in newer branches;
367 it's needed since many platforms are adopting newer OpenSSL versions.
373 Support Tcl 8.6 in MSVC builds (Álvaro Herrera)
379 Sync our copy of the timezone library with IANA release tzcode2017b
384 This fixes a bug affecting some DST transitions in January 2038.
390 Update time zone data files to <application>tzdata</> release 2017b
391 for DST law changes in Chile, Haiti, and Mongolia, plus historical
392 corrections for Ecuador, Kazakhstan, Liberia, and Spain.
393 Switch to numeric abbreviations for numerous time zones in South
394 America, the Pacific and Indian oceans, and some Asian and Middle
399 The IANA time zone database previously provided textual abbreviations
400 for all time zones, sometimes making up abbreviations that have little
401 or no currency among the local population. They are in process of
402 reversing that policy in favor of using numeric UTC offsets in zones
403 where there is no evidence of real-world use of an English
404 abbreviation. At least for the time being, <productname>PostgreSQL</>
405 will continue to accept such removed abbreviations for timestamp input.
406 But they will not be shown in the <structname>pg_timezone_names</>
407 view nor used for output.
413 Use correct daylight-savings rules for POSIX-style time zone names
414 in MSVC builds (David Rowley)
418 The Microsoft MSVC build scripts neglected to install
419 the <filename>posixrules</> file in the timezone directory tree.
420 This resulted in the timezone code falling back to its built-in
421 rule about what DST behavior to assume for a POSIX-style time zone
422 name. For historical reasons that still corresponds to the DST rules
423 the USA was using before 2007 (i.e., change on first Sunday in April
424 and last Sunday in October). With this fix, a POSIX-style zone name
425 will use the current and historical DST transition dates of
426 the <literal>US/Eastern</> zone. If you don't want that, remove
427 the <filename>posixrules</> file, or replace it with a copy of some
428 other zone file (see <xref linkend="datatype-timezones">). Note that
429 due to caching, you may need to restart the server to get such changes

449 For information about new features in the 9.4 major release, see
450 <xref linkend="release-9-4">.
454 <title>Migration to Version 9.4.11</title>
457 A dump/restore is not required for those running 9.4.X.
461 However, if your installation has been affected by the bug described in
462 the first changelog entry below, then after updating you may need
463 to take action to repair corrupted indexes.
467 Also, if you are upgrading from a version earlier than 9.4.10,
468 see <xref linkend="release-9-4-10">.
473 <title>Changes</title>
479 Fix a race condition that could cause indexes built
480 with <command>CREATE INDEX CONCURRENTLY</> to be corrupt
481 (Pavan Deolasee, Tom Lane)
485 If <command>CREATE INDEX CONCURRENTLY</> was used to build an index
486 that depends on a column not previously indexed, then rows
487 updated by transactions that ran concurrently with
488 the <command>CREATE INDEX</> command could have received incorrect
489 index entries. If you suspect this may have happened, the most
490 reliable solution is to rebuild affected indexes after installing
497 Ensure that the special snapshot used for catalog scans is not
498 invalidated by premature data pruning (Tom Lane)
502 Backends failed to account for this snapshot when advertising their
503 oldest xmin, potentially allowing concurrent vacuuming operations to
504 remove data that was still needed. This led to transient failures
505 along the lines of <quote>cache lookup failed for relation 1255</>.
511 Unconditionally WAL-log creation of the <quote>init fork</> for an
512 unlogged table (Michael Paquier)
516 Previously, this was skipped when <xref linkend="guc-wal-level">
517 = <literal>minimal</>, but actually it's necessary even in that case
518 to ensure that the unlogged table is properly reset to empty after a
525 Reduce interlocking on standby servers during the replay of btree
526 index vacuuming operations (Simon Riggs)
530 This change avoids substantial replication delays that sometimes
531 occurred while replaying such operations.
537 If the stats collector dies during hot standby, restart it (Takayuki
544 Ensure that hot standby feedback works correctly when it's enabled at
545 standby server start (Ants Aasma, Craig Ringer)
551 Check for interrupts while hot standby is waiting for a conflicting
558 Avoid constantly respawning the autovacuum launcher in a corner case
563 This fix avoids problems when autovacuum is nominally off and there
564 are some tables that require freezing, but all such tables are
565 already being processed by autovacuum workers.
571 Fix check for when an extension member object can be dropped (Tom Lane)
575 Extension upgrade scripts should be able to drop member objects,
576 but this was disallowed for serial-column sequences, and possibly
583 Make sure <command>ALTER TABLE</> preserves index tablespace
584 assignments when rebuilding indexes (Tom Lane, Michael Paquier)
588 Previously, non-default settings
589 of <xref linkend="guc-default-tablespace"> could result in broken
596 Fix incorrect updating of trigger function properties when changing a
597 foreign-key constraint's deferrability properties with <command>ALTER
598 TABLE ... ALTER CONSTRAINT</> (Tom Lane)
602 This led to odd failures during subsequent exercise of the foreign
603 key, as the triggers were fired at the wrong times.
609 Prevent dropping a foreign-key constraint if there are pending
610 trigger events for the referenced relation (Tom Lane)
614 This avoids <quote>could not find trigger <replaceable>NNN</></quote>
615 or <quote>relation <replaceable>NNN</> has no triggers</quote> errors.
621 Fix processing of OID column when a table with OIDs is associated to
622 a parent with OIDs via <command>ALTER TABLE ... INHERIT</> (Amit
627 The OID column should be treated the same as regular user columns in
628 this case, but it wasn't, leading to odd behavior in later
635 Fix <command>CREATE OR REPLACE VIEW</> to update the view query
636 before attempting to apply the new view options (Dean Rasheed)
640 Previously the command would fail if the new options were
641 inconsistent with the old view definition.
647 Report correct object identity during <command>ALTER TEXT SEARCH
648 CONFIGURATION</> (Artur Zakirov)
652 The wrong catalog OID was reported to extensions such as logical
659 Check for serializability conflicts before reporting
660 constraint-violation failures (Thomas Munro)
664 When using serializable transaction isolation, it is desirable
665 that any error due to concurrent transactions should manifest
666 as a serialization failure, thereby cueing the application that
667 a retry might succeed. Unfortunately, this does not reliably
668 happen for duplicate-key failures caused by concurrent insertions.
669 This change ensures that such an error will be reported as a
670 serialization error if the application explicitly checked for
671 the presence of a conflicting key (and did not find it) earlier
678 Prevent multicolumn expansion of <replaceable>foo</><literal>.*</> in
679 an <command>UPDATE</> source expression (Tom Lane)
683 This led to <quote>UPDATE target count mismatch --- internal
684 error</>. Now the syntax is understood as a whole-row variable,
685 as it would be in other contexts.
691 Ensure that column typmods are determined accurately for
692 multi-row <literal>VALUES</> constructs (Tom Lane)
696 This fixes problems occurring when the first value in a column has a
697 determinable typmod (e.g., length for a <type>varchar</> value) but
698 later values don't share the same limit.
704 Throw error for an unfinished Unicode surrogate pair at the end of a
705 Unicode string (Tom Lane)
709 Normally, a Unicode surrogate leading character must be followed by a
710 Unicode surrogate trailing character, but the check for this was
711 missed if the leading character was the last character in a Unicode
712 string literal (<literal>U&'...'</>) or Unicode identifier
713 (<literal>U&"..."</>).
719 Ensure that a purely negative text search query, such
720 as <literal>!foo</>, matches empty <type>tsvector</>s (Tom Dunstan)
724 Such matches were found by GIN index searches, but not by sequential
725 scans or GiST index searches.
731 Prevent crash when <function>ts_rewrite()</> replaces a non-top-level
732 subtree with an empty query (Artur Zakirov)
738 Fix performance problems in <function>ts_rewrite()</> (Tom Lane)
744 Fix <function>ts_rewrite()</>'s handling of nested NOT operators
751 Fix <function>array_fill()</> to handle empty arrays properly (Tom Lane)
757 Fix one-byte buffer overrun in <function>quote_literal_cstr()</>
762 The overrun occurred only if the input consisted entirely of single
763 quotes and/or backslashes.
769 Prevent multiple calls of <function>pg_start_backup()</>
770 and <function>pg_stop_backup()</> from running concurrently (Michael
775 This avoids an assertion failure, and possibly worse things, if
776 someone tries to run these functions in parallel.
782 Avoid discarding <type>interval</>-to-<type>interval</> casts
783 that aren't really no-ops (Tom Lane)
787 In some cases, a cast that should result in zeroing out
788 low-order <type>interval</> fields was mistakenly deemed to be a
789 no-op and discarded. An example is that casting from <type>INTERVAL
790 MONTH</> to <type>INTERVAL YEAR</> failed to clear the months field.
796 Ensure that cached plans are invalidated by changes in foreign-table
797 options (Amit Langote, Etsuro Fujita, Ashutosh Bapat)
803 Fix <application>pg_dump</> to dump user-defined casts and transforms
804 that use built-in functions (Stephen Frost)
810 Fix <application>pg_restore</> with <option>--create --if-exists</>
811 to behave more sanely if an archive contains
812 unrecognized <command>DROP</> commands (Tom Lane)
816 This doesn't fix any live bug, but it may improve the behavior in
817 future if <application>pg_restore</> is used with an archive
818 generated by a later <application>pg_dump</> version.
824 Fix <application>pg_basebackup</>'s rate limiting in the presence of
825 slow I/O (Antonin Houska)
829 If disk I/O was transiently much slower than the specified rate
830 limit, the calculation overflowed, effectively disabling the rate
831 limit for the rest of the run.
837 Fix <application>pg_basebackup</>'s handling of
838 symlinked <filename>pg_stat_tmp</> and <filename>pg_replslot</>
839 subdirectories (Magnus Hagander, Michael Paquier)
845 Fix possible <application>pg_basebackup</> failure on standby
846 server when including WAL files (Amit Kapila, Robert Haas)
852 Ensure that the Python exception objects we create for PL/Python are
853 properly reference-counted (Rafa de la Torre, Tom Lane)
857 This avoids failures if the objects are used after a Python garbage
858 collection cycle has occurred.
864 Fix PL/Tcl to support triggers on tables that have <literal>.tupno</>
865 as a column name (Tom Lane)
869 This matches the (previously undocumented) behavior of
870 PL/Tcl's <command>spi_exec</> and <command>spi_execp</> commands,
871 namely that a magic <literal>.tupno</> column is inserted only if
872 there isn't a real column named that.
878 Allow DOS-style line endings in <filename>~/.pgpass</> files,
879 even on Unix (Vik Fearing)
883 This change simplifies use of the same password file across Unix and
890 Fix one-byte buffer overrun if <application>ecpg</> is given a file
891 name that ends with a dot (Takayuki Tsunakawa)
897 Fix <application>psql</>'s tab completion for <command>ALTER DEFAULT
898 PRIVILEGES</> (Gilles Darold, Stephen Frost)
904 In <application>psql</>, treat an empty or all-blank setting of
905 the <envar>PAGER</> environment variable as meaning <quote>no
910 Previously, such a setting caused output intended for the pager to
917 Improve <filename>contrib/dblink</>'s reporting of
918 low-level <application>libpq</> errors, such as out-of-memory
925 Teach <filename>contrib/dblink</> to ignore irrelevant server options
926 when it uses a <filename>contrib/postgres_fdw</> foreign server as
927 the source of connection options (Corey Huinker)
931 Previously, if the foreign server object had options that were not
932 also <application>libpq</> connection options, an error occurred.
938 On Windows, ensure that environment variable changes are propagated
939 to DLLs built with debug options (Christian Ullrich)
945 Sync our copy of the timezone library with IANA release tzcode2016j
950 This fixes various issues, most notably that timezone data
951 installation failed if the target directory didn't support hard
958 Update time zone data files to <application>tzdata</> release 2016j
959 for DST law changes in northern Cyprus (adding a new zone
960 Asia/Famagusta), Russia (adding a new zone Europe/Saratov), Tonga,
961 and Antarctica/Casey.
962 Historical corrections for Italy, Kazakhstan, Malta, and Palestine.
963 Switch to preferring numeric zone abbreviations for Tonga.

987 <title>Migration to Version 9.4.10</title>
990 A dump/restore is not required for those running 9.4.X.
994 However, if your installation has been affected by the bug described in
995 the first changelog entry below, then after updating you may need
996 to take action to repair corrupted free space maps.
1000 Also, if you are upgrading from a version earlier than 9.4.6,
1001 see <xref linkend="release-9-4-6">.
1006 <title>Changes</title>
1012 Fix WAL-logging of truncation of relation free space maps and
1013 visibility maps (Pavan Deolasee, Heikki Linnakangas)
1017 It was possible for these files to not be correctly restored during
1018 crash recovery, or to be written incorrectly on a standby server.
1019 Bogus entries in a free space map could lead to attempts to access
1020 pages that have been truncated away from the relation itself, typically
1021 producing errors like <quote>could not read block <replaceable>XXX</>:
1022 read only 0 of 8192 bytes</quote>. Checksum failures in the
1023 visibility map are also possible, if checksumming is enabled.
1027 Procedures for determining whether there is a problem and repairing it
1028 if so are discussed at
1029 <ulink url="https://wiki.postgresql.org/wiki/Free_Space_Map_Problems"></>.
1035 Fix incorrect creation of GIN index WAL records on big-endian machines
1040 The typical symptom was <quote>unexpected GIN leaf action</> errors
1047 Fix <command>SELECT FOR UPDATE/SHARE</> to correctly lock tuples that
1048 have been updated by a subsequently-aborted transaction
1049 (Álvaro Herrera)
1053 In 9.5 and later, the <command>SELECT</> would sometimes fail to
1054 return such tuples at all. A failure has not been proven to occur in
1055 earlier releases, but might be possible with concurrent updates.
1061 Fix EvalPlanQual rechecks involving CTE scans (Tom Lane)
1065 The recheck would always see the CTE as returning no rows, typically
1066 leading to failure to update rows that were recently updated.
1072 Fix improper repetition of previous results from hashed aggregation in
1073 a subquery (Andrew Gierth)
1077 The test to see if we can reuse a previously-computed hash table of
1078 the aggregate state values neglected the possibility of an outer query
1079 reference appearing in an aggregate argument expression. A change in
1080 the value of such a reference should lead to recalculating the hash
1087 Fix query-lifespan memory leak in a bulk <command>UPDATE</> on a table
1088 with a <literal>PRIMARY KEY</> or <literal>REPLICA IDENTITY</> index
1095 Fix <command>EXPLAIN</> to emit valid XML when
1096 <xref linkend="guc-track-io-timing"> is on (Markus Winand)
1100 Previously the XML output-format option produced syntactically invalid
1101 tags such as <literal><I/O-Read-Time></>. That is now
1102 rendered as <literal><I-O-Read-Time></>.
1108 Suppress printing of zeroes for unmeasured times
1109 in <command>EXPLAIN</> (Maksim Milyutin)
1113 Certain option combinations resulted in printing zero values for times
1114 that actually aren't ever measured in that combination. Our general
1115 policy in <command>EXPLAIN</> is not to print such fields at all, so
1116 do that consistently in all cases.
1122 Fix timeout length when <command>VACUUM</> is waiting for exclusive
1123 table lock so that it can truncate the table (Simon Riggs)
1127 The timeout was meant to be 50 milliseconds, but it was actually only
1128 50 microseconds, causing <command>VACUUM</> to give up on truncation
1129 much more easily than intended. Set it to the intended value.
1135 Fix bugs in merging inherited <literal>CHECK</> constraints while
1136 creating or altering a table (Tom Lane, Amit Langote)
1140 Allow identical <literal>CHECK</> constraints to be added to a parent
1141 and child table in either order. Prevent merging of a valid
1142 constraint from the parent table with a <literal>NOT VALID</>
1143 constraint on the child. Likewise, prevent merging of a <literal>NO
1144 INHERIT</> child constraint with an inherited constraint.
1150 Remove artificial restrictions on the values accepted
1151 by <function>numeric_in()</> and <function>numeric_recv()</>
1156 We allow numeric values up to the limit of the storage format (more
1157 than <literal>1e100000</>), so it seems fairly pointless

1189 Logical decoding of a tuple update record read 23 bytes too many,
1190 which was usually harmless but with very bad luck could result in a

1198 more than 1GB (Andres Freund)
1204 Disallow starting a standalone backend with <literal>standby_mode</>
1205 turned on (Michael Paquier)
1209 This can't do anything useful, since there will be no WAL receiver
1210 process to fetch more WAL data; and it could result in misbehavior
1211 in code that wasn't designed with this situation in mind.
1217 Properly initialize replication slot state when recycling a
1218 previously-used slot (Michael Paquier)
1222 This failure to reset all of the fields of the slot could
1223 prevent <command>VACUUM</> from removing dead tuples.
1229 Round shared-memory allocation request to a multiple of the actual
1230 huge page size when attempting to use huge pages on Linux (Tom Lane)
1234 This avoids possible failures during <function>munmap()</> on systems
1235 with atypical default huge page sizes. Except in crash-recovery
1236 cases, there were no ill effects other than a log message.
1242 Use a more random value for the dynamic shared memory control
1243 segment's ID (Robert Haas, Tom Lane)
1247 Previously, the same value would be chosen every time, because it was
1248 derived from <function>random()</> but <function>srandom()</> had not
1249 yet been called. While relatively harmless, this was not the intended
1256 On Windows, retry creation of the dynamic shared memory control
1257 segment after an access-denied error (Kyotaro Horiguchi, Amit Kapila)
1261 Windows sometimes returns <literal>ERROR_ACCESS_DENIED</> rather
1262 than <literal>ERROR_ALREADY_EXISTS</> when there is an existing
1263 segment. This led to postmaster startup failure due to believing that
1264 the former was an unrecoverable error.
1270 Don't try to share SSL contexts across multiple connections
1271 in <application>libpq</> (Heikki Linnakangas)
1275 This led to assorted corner-case bugs, particularly when trying to use
1276 different SSL parameters for different connections.
1282 Avoid corner-case memory leak in <application>libpq</> (Tom Lane)
1286 The reported problem involved leaking an error report
1287 during <function>PQreset()</>, but there might be related cases.
1293 Make <application>ecpg</>'s <option>--help</> and <option>--version</>
1294 options work consistently with our other executables (Haribabu Kommi)
1300 Fix <application>pgbench</>'s calculation of average latency
1305 The calculation was incorrect when there were <literal>\sleep</>
1306 commands in the script, or when the test duration was specified in
1307 number of transactions rather than total time.
1313 In <application>pg_dump</>, never dump range constructor functions
1318 This oversight led to <application>pg_upgrade</> failures with
1319 extensions containing range types, due to duplicate creation of the
1320 constructor functions.
1326 In <application>pg_xlogdump</>, retry opening new WAL segments when
1327 using <option>--follow</> option (Magnus Hagander)

1367 with <option>--enable-tap-tests</>, <quote>make install</> will now
1368 install the Perl support files for TAP testing where PGXS can find
1369 them. This allows non-core extensions to
1370 use <literal>$(prove_check)</> without extra tests.

1377 client-only installation (MauMau)
1383 Update Windows time zone mapping to recognize some time zone names
1384 added in recent Windows versions (Michael Paquier)
1390 Prevent failure of obsolete dynamic time zone abbreviations (Tom Lane)
1394 If a dynamic time zone abbreviation does not match any entry in the
1395 referenced time zone, treat it as equivalent to the time zone name.
1396 This avoids unexpected failures when IANA removes abbreviations from
1397 their time zone database, as they did in <application>tzdata</>
1398 release 2016f and seem likely to do again in the future. The
1399 consequences were not limited to not recognizing the individual
1400 abbreviation; any mismatch caused
1401 the <structname>pg_timezone_abbrevs</> view to fail altogether.
1407 Update time zone data files to <application>tzdata</> release 2016h
1408 for DST law changes in Palestine and Turkey, plus historical
1409 corrections for Turkey and some regions of Russia.
1410 Switch to numeric abbreviations for some time zones in Antarctica,
1411 the former Soviet Union, and Sri Lanka.
1415 The IANA time zone database previously provided textual abbreviations
1416 for all time zones, sometimes making up abbreviations that have little
1417 or no currency among the local population. They are in process of
1418 reversing that policy in favor of using numeric UTC offsets in zones
1419 where there is no evidence of real-world use of an English
1420 abbreviation. At least for the time being, <productname>PostgreSQL</>
1421 will continue to accept such removed abbreviations for timestamp input.
1422 But they will not be shown in the <structname>pg_timezone_names</>
1423 view nor used for output.
1427 In this update, <literal>AMT</> is no longer shown as being in use to
1428 mean Armenia Time. Therefore, we have changed the <literal>Default</>
1429 abbreviation set to interpret it as Amazon Time, thus UTC-4 not UTC+4.

1456 A dump/restore is not required for those running 9.4.X.
1460 However, if you are upgrading from a version earlier than 9.4.6,
1461 see <xref linkend="release-9-4-6">.
1466 <title>Changes</title>
1472 Fix possible mis-evaluation of
1473 nested <literal>CASE</>-<literal>WHEN</> expressions (Heikki
1474 Linnakangas, Michael Paquier, Tom Lane)
1478 A <literal>CASE</> expression appearing within the test value
1479 subexpression of another <literal>CASE</> could become confused about
1480 whether its own test value was null or not. Also, inlining of a SQL
1481 function implementing the equality operator used by
1482 a <literal>CASE</> expression could result in passing the wrong test
1483 value to functions called within a <literal>CASE</> expression in the
1484 SQL function's body. If the test values were of different data
1485 types, a crash might result; moreover such situations could be abused
1486 to allow disclosure of portions of server memory. (CVE-2016-5423)
1492 Fix client programs' handling of special characters in database and
1493 role names (Noah Misch, Nathan Bossart, Michael Paquier)
1497 Numerous places in <application>vacuumdb</> and other client programs
1498 could become confused by database and role names containing double
1499 quotes or backslashes. Tighten up quoting rules to make that safe.
1500 Also, ensure that when a conninfo string is used as a database name
1501 parameter to these programs, it is correctly treated as such throughout.
1505 Fix handling of paired double quotes
1506 in <application>psql</>'s <command>\connect</>
1507 and <command>\password</> commands to match the documentation.
1511 Introduce a new <option>-reuse-previous</> option
1512 in <application>psql</>'s <command>\connect</> command to allow
1513 explicit control of whether to re-use connection parameters from a
1514 previous connection. (Without this, the choice is based on whether
1515 the database name looks like a conninfo string, as before.) This
1516 allows secure handling of database names containing special
1517 characters in <application>pg_dumpall</> scripts.
1521 <application>pg_dumpall</> now refuses to deal with database and role
1522 names containing carriage returns or newlines, as it seems impractical
1523 to quote those characters safely on Windows. In future we may reject
1524 such names on the server side, but that step has not been taken yet.
1528 These are considered security fixes because crafted object names
1529 containing special characters could have been used to execute
1530 commands with superuser privileges the next time a superuser
1531 executes <application>pg_dumpall</> or other routine maintenance
1532 operations. (CVE-2016-5424)
1538 Fix corner-case misbehaviors for <literal>IS NULL</>/<literal>IS NOT
1539 NULL</> applied to nested composite values (Andrew Gierth, Tom Lane)
1543 The SQL standard specifies that <literal>IS NULL</> should return
1544 TRUE for a row of all null values (thus <literal>ROW(NULL,NULL) IS
1545 NULL</> yields TRUE), but this is not meant to apply recursively
1546 (thus <literal>ROW(NULL, ROW(NULL,NULL)) IS NULL</> yields FALSE).
1547 The core executor got this right, but certain planner optimizations
1548 treated the test as recursive (thus producing TRUE in both cases),
1549 and <filename>contrib/postgres_fdw</> could produce remote queries
1550 that misbehaved similarly.
1556 Make the <type>inet</> and <type>cidr</> data types properly reject
1557 IPv6 addresses with too many colon-separated fields (Tom Lane)
1563 Prevent crash in <function>close_ps()</>
1564 (the <type>point</> <literal>##</> <type>lseg</> operator)
1565 for NaN input coordinates (Tom Lane)
1569 Make it return NULL instead of crashing.
1575 Avoid possible crash in <function>pg_get_expr()</> when inconsistent
1576 values are passed to it (Michael Paquier, Thomas Munro)
1582 Fix several one-byte buffer over-reads in <function>to_number()</>
1587 In several cases the <function>to_number()</> function would read one
1588 more character than it should from the input string. There is a
1589 small chance of a crash, if the input happens to be adjacent to the
1596 Do not run the planner on the query contained in <literal>CREATE
1597 MATERIALIZED VIEW</> or <literal>CREATE TABLE AS</>
1598 when <literal>WITH NO DATA</> is specified (Michael Paquier,
1603 This avoids some unnecessary failure conditions, for example if a
1604 stable function invoked by the materialized view depends on a table
1605 that doesn't exist yet.
1611 Avoid unsafe intermediate state during expensive paths
1612 through <function>heap_update()</> (Masahiko Sawada, Andres Freund)
1616 Previously, these cases locked the target tuple (by setting its XMAX)
1617 but did not WAL-log that action, thus risking data integrity problems
1618 if the page were spilled to disk and then a database crash occurred
1619 before the tuple update could be completed.
1625 Fix hint bit update during WAL replay of row locking operations
1630 The only known consequence of this problem is that row locks held by
1631 a prepared, but uncommitted, transaction might fail to be enforced
1632 after a crash and restart.
1638 Avoid unnecessary <quote>could not serialize access</> errors when
1639 acquiring <literal>FOR KEY SHARE</> row locks in serializable mode
1640 (Álvaro Herrera)
1646 Avoid crash in <literal>postgres -C</> when the specified variable
1647 has a null string value (Michael Paquier)
1653 Fix possible loss of large subtransactions in logical decoding
1654 (Petru-Florin Mihancea)
1660 Fix failure of logical decoding when a subtransaction contains no
1661 actual changes (Marko Tiikkaja, Andrew Gierth)
1667 Ensure that backends see up-to-date statistics for shared catalogs
1672 The statistics collector failed to update the statistics file for
1673 shared catalogs after a request from a regular backend. This problem
1674 was partially masked because the autovacuum launcher regularly makes
1675 requests that did cause such updates; however, it became obvious with
1676 autovacuum disabled.
1682 Avoid redundant writes of the statistics files when multiple
1683 backends request updates close together (Tom Lane, Tomas Vondra)
1689 Avoid consuming a transaction ID during <command>VACUUM</>
1690 (Alexander Korotkov)
1694 Some cases in <command>VACUUM</> unnecessarily caused an XID to be
1695 assigned to the current transaction. Normally this is negligible,
1696 but if one is up against the XID wraparound limit, consuming more
1697 XIDs during anti-wraparound vacuums is a very bad thing.

1715 <command>VACUUM FREEZE</> on an otherwise-idle master server could

1723 Prevent possible failure when vacuuming multixact IDs in an
1724 installation that has been pg_upgrade'd from pre-9.3 (Andrew Gierth,

1757 values, leading to serious planner misestimates in some types of
1764 Prevent autovacuum from starting multiple workers for the same shared
1765 catalog (Álvaro Herrera)
1769 Normally this isn't much of a problem because the vacuum doesn't take
1770 long anyway; but in the case of a severely bloated catalog, it could
1771 result in all but one worker uselessly waiting instead of doing
1772 useful work on other tables.
1778 Avoid duplicate buffer lock release when abandoning a b-tree index
1779 page deletion attempt (Tom Lane)
1783 This mistake prevented <command>VACUUM</> from completing in some

1840 to send query-cancel requests to the connected backends, in case they
1841 are doing something long-running such as a <command>CREATE INDEX</>.
1847 Fix error reporting in parallel <application>pg_dump</>
1848 and <application>pg_restore</> (Tom Lane)
1852 Previously, errors reported by <application>pg_dump</>
1853 or <application>pg_restore</> worker processes might never make it to
1854 the user's console, because the messages went through the master
1855 process, and there were various deadlock scenarios that would prevent
1856 the master process from passing on the messages. Instead, just print
1857 everything to <literal>stderr</>. In some cases this will result in
1858 duplicate messages (for instance, if all the workers report a server
1859 shutdown), but that seems better than no message.
1865 Ensure that parallel <application>pg_dump</>
1866 or <application>pg_restore</> on Windows will shut down properly
1867 after an error (Kyotaro Horiguchi)
1871 Previously, it would report the error, but then just sit until
1872 manually stopped by the user.
1878 Make <application>pg_dump</> behave better when built without zlib
1879 support (Kyotaro Horiguchi)
1883 It didn't work right for parallel dumps, and emitted some rather
1884 pointless warnings in other cases.

1905 name contains spaces (Michael Paquier, Kyotaro Horiguchi)
1911 Be more predictable about reporting <quote>statement timeout</>
1912 versus <quote>lock timeout</> (Tom Lane)
1916 On heavily loaded machines, the regression tests sometimes failed due
1917 to reporting <quote>lock timeout</> even though the statement timeout
1918 should have occurred first.

1988 <title>Changes</title>
1994 Clear the OpenSSL error queue before OpenSSL calls, rather than
1995 assuming it's clear already; and make sure we leave it clear
1996 afterwards (Peter Geoghegan, Dave Vitek, Peter Eisentraut)
2000 This change prevents problems when there are multiple connections
2001 using OpenSSL within a single process and not all the code involved
2002 follows the same rules for when to clear the error queue.
2003 Failures have been reported specifically when a client application
2004 uses SSL connections in <application>libpq</> concurrently with
2005 SSL connections using the PHP, Python, or Ruby wrappers for OpenSSL.
2006 It's possible for similar problems to arise within the server as well,
2007 if an extension module establishes an outgoing SSL connection.
2013 Fix <quote>failed to build any <replaceable>N</>-way joins</quote>
2014 planner error with a full join enclosed in the right-hand side of a
2015 left join (Tom Lane)
2021 Fix incorrect handling of equivalence-class tests in multilevel
2022 nestloop plans (Tom Lane)
2026 Given a three-or-more-way equivalence class of variables, such
2027 as <literal>X.X = Y.Y = Z.Z</>, it was possible for the planner to omit
2028 some of the tests needed to enforce that all the variables are actually
2029 equal, leading to join rows being output that didn't satisfy
2030 the <literal>WHERE</> clauses. For various reasons, erroneous plans
2031 were seldom selected in practice, so that this bug has gone undetected
2038 Fix query-lifespan memory leak in GIN index scans (Julien Rouhaud)
2044 Fix query-lifespan memory leak and potential index corruption hazard in
2045 GIN index insertion (Tom Lane)
2049 The memory leak would typically not amount to much in simple queries,
2050 but it could be very substantial during a large GIN index build with
2051 high <varname>maintenance_work_mem</>.
2057 Fix possible misbehavior of <literal>TH</>, <literal>th</>,
2058 and <literal>Y,YYY</> format codes in <function>to_timestamp()</>
2063 These could advance off the end of the input string, causing subsequent
2064 format codes to read garbage.
2070 Fix dumping of rules and views in which the <replaceable>array</>
2071 argument of a <literal><replaceable>value</> <replaceable>operator</>
2072 ANY (<replaceable>array</>)</literal> construct is a sub-SELECT
2079 Disallow newlines in <command>ALTER SYSTEM</> parameter values
2084 The configuration-file parser doesn't support embedded newlines in
2085 string literals, so we mustn't allow them in values to be inserted
2086 by <command>ALTER SYSTEM</>.
2092 Fix <command>ALTER TABLE ... REPLICA IDENTITY USING INDEX</> to
2093 work properly if an index on OID is selected (David Rowley)
2099 Fix crash in logical decoding on alignment-picky platforms (Tom Lane,
2104 The failure occurred only with a transaction large enough to spill to
2105 disk and a primary-key change within that transaction.
2111 Avoid repeated requests for feedback from receiver while shutting down
2112 walsender (Nick Cleaton)
2118 Make <application>pg_regress</> use a startup timeout from the
2119 <envar>PGCTLTIMEOUT</> environment variable, if that's set (Tom Lane)
2123 This is for consistency with a behavior recently added
2124 to <application>pg_ctl</>; it eases automated testing on slow machines.
2130 Fix <application>pg_upgrade</> to correctly restore extension
2131 membership for operator families containing only one operator class
2136 In such a case, the operator family was restored into the new database,
2137 but it was no longer marked as part of the extension. This had no
2138 immediate ill effects, but would cause later <application>pg_dump</>
2139 runs to emit output that would cause (harmless) errors on restore.
2145 Fix <application>pg_upgrade</> to not fail when new-cluster TOAST rules
2146 differ from old (Tom Lane)
2150 <application>pg_upgrade</> had special-case code to handle the
2151 situation where the new <productname>PostgreSQL</> version thinks that
2152 a table should have a TOAST table while the old version did not. That
2153 code was broken, so remove it, and instead do nothing in such cases;
2154 there seems no reason to believe that we can't get along fine without
2155 a TOAST table if that was okay according to the old version's rules.

2233 For information about new features in the 9.4 major release, see
2234 <xref linkend="release-9-4">.
2238 <title>Migration to Version 9.4.7</title>
2241 A dump/restore is not required for those running 9.4.X.

2251 <title>Changes</title>
2257 Fix incorrect handling of NULL index entries in
2258 indexed <literal>ROW()</> comparisons (Tom Lane)
2262 An index search using a row comparison such as <literal>ROW(a, b) >
2263 ROW('x', 'y')</> would stop upon reaching a NULL entry in
2264 the <structfield>b</> column, ignoring the fact that there might be
2265 non-NULL <structfield>b</> values associated with later values
2266 of <structfield>a</>.
2272 Avoid unlikely data-loss scenarios due to renaming files without
2273 adequate <function>fsync()</> calls before and after (Michael Paquier,
2274 Tomas Vondra, Andres Freund)
2280 Fix bug in <function>json_to_record()</> when a field of its input
2281 object contains a sub-object with a field name matching one of the
2282 requested output column names (Tom Lane)
2288 Fix misformatting of negative time zone offsets
2289 by <function>to_char()</>'s <literal>OF</> format code
2290 (Thomas Munro, Tom Lane)
2296 Ignore <xref linkend="recovery-min-apply-delay"> parameter until
2297 recovery has reached a consistent state (Michael Paquier)
2301 Previously, standby servers would delay application of WAL records in
2302 response to <varname>recovery_min_apply_delay</> even while replaying
2303 the initial portion of WAL needed to make their database state valid.
2304 Since the standby is useless until it's reached a consistent database
2305 state, this was deemed unhelpful.
2311 Correctly handle cases where <literal>pg_subtrans</> is close to XID
2312 wraparound during server startup (Jeff Janes)
2318 Fix assorted bugs in logical decoding (Andres Freund)
2322 Trouble cases included tuples larger than one page when replica
2323 identity is <literal>FULL</>, <command>UPDATE</>s that change a
2324 primary key within a transaction large enough to be spooled to disk,
2325 incorrect reports of <quote>subxact logged without previous toplevel
2326 record</>, and incorrect reporting of a transaction's commit time.
2332 Fix planner error with nested security barrier views when the outer
2333 view has a <literal>WHERE</> clause containing a correlated subquery
2340 Fix corner-case crash due to trying to free <function>localeconv()</>
2341 output strings more than once (Tom Lane)
2347 Fix parsing of affix files for <literal>ispell</> dictionaries
2352 The code could go wrong if the affix file contained any characters
2353 whose byte length changes during case-folding, for
2354 example <literal>I</> in Turkish UTF8 locales.
2360 Avoid use of <function>sscanf()</> to parse <literal>ispell</>
2361 dictionary files (Artur Zakirov)
2365 This dodges a portability problem on FreeBSD-derived platforms
2372 Avoid a crash on old Windows versions (before 7SP1/2008R2SP1) with an
2373 AVX2-capable CPU and a Postgres build done with Visual Studio 2013
2378 This is a workaround for a bug in Visual Studio 2013's runtime
2379 library, which Microsoft have stated they will not fix in that
2386 Fix <application>psql</>'s tab completion logic to handle multibyte
2387 characters properly (Kyotaro Horiguchi, Robert Haas)
2393 Fix <application>psql</>'s tab completion for
2394 <literal>SECURITY LABEL</> (Tom Lane)
2398 Pressing TAB after <literal>SECURITY LABEL</> might cause a crash
2399 or offering of inappropriate keywords.
2405 Make <application>pg_ctl</> accept a wait timeout from the
2406 <envar>PGCTLTIMEOUT</> environment variable, if none is specified on
2407 the command line (Noah Misch)
2411 This eases testing of slower buildfarm members by allowing them
2412 to globally specify a longer-than-normal timeout for postmaster
2413 startup and shutdown.
2419 Fix incorrect test for Windows service status
2420 in <application>pg_ctl</> (Manuel Mathar)
2424 The previous set of minor releases attempted to
2425 fix <application>pg_ctl</> to properly determine whether to send log
2426 messages to Window's Event Log, but got the test backwards.
2432 Fix <application>pgbench</> to correctly handle the combination
2433 of <literal>-C</> and <literal>-M prepared</> options (Tom Lane)
2439 In <application>pg_upgrade</>, skip creating a deletion script when
2440 the new data directory is inside the old data directory (Bruce
2445 Blind application of the script in such cases would result in loss of
2446 the new data directory.
2452 In PL/Perl, properly translate empty Postgres arrays into empty Perl
2453 arrays (Alex Hunsaker)
2459 Make PL/Python cope with function names that aren't valid Python
2460 identifiers (Jim Nasby)
2466 Fix multiple mistakes in the statistics returned
2467 by <filename>contrib/pgstattuple</>'s <function>pgstatindex()</>
2474 Remove dependency on <literal>psed</> in MSVC builds, since it's no
2475 longer provided by core Perl (Michael Paquier, Andrew Dunstan)
2481 Update time zone data files to <application>tzdata</> release 2016c
2482 for DST law changes in Azerbaijan, Chile, Haiti, Palestine, and Russia
2483 (Altai, Astrakhan, Kirov, Sakhalin, Ulyanovsk regions), plus
2484 historical corrections for Lithuania, Moldova, and Russia
2485 (Kaliningrad, Samara, Volgograd).

2512 A dump/restore is not required for those running 9.4.X.

2517 indexes that use the (non-default) <literal>jsonb_path_ops</> operator
2518 class, see the first changelog entry below.

2541 Fix inconsistent hash calculations in <literal>jsonb_path_ops</> GIN
2546 When processing <type>jsonb</> values that contain both scalars and
2547 sub-objects at the same nesting level, for example an array containing
2548 both scalars and sub-arrays, key hash values could be calculated
2549 differently than they would be for the same key in a different context.
2550 This could result in queries not finding entries that they should find.
2551 Fixing this means that existing indexes may now be inconsistent with the
2552 new hash calculation code. Users
2553 should <command>REINDEX</> <literal>jsonb_path_ops</> GIN indexes after
2554 installing this update to make sure that all searches work as expected.
2560 Fix infinite loops and buffer-overrun problems in regular expressions
2565 Very large character ranges in bracket expressions could cause
2566 infinite loops in some cases, and memory overwrites in other cases.

2583 Perform an immediate shutdown if the <filename>postmaster.pid</> file
2584 is removed (Tom Lane)
2588 The postmaster now checks every minute or so
2589 that <filename>postmaster.pid</> is still there and still contains its
2590 own PID. If not, it performs an immediate shutdown, as though it had
2591 received <systemitem>SIGQUIT</>. The main motivation for this change
2592 is to ensure that failed buildfarm runs will get cleaned up without
2593 manual intervention; but it also serves to limit the bad effects if a
2594 DBA forcibly removes <filename>postmaster.pid</> and then starts a new

2937 The code added for CVE-2007-4772 was both incomplete, in that it didn't
2938 handle loops involving more than one state, and incorrect, in that it
2939 could cause assertion failures (though there seem to be no bad
2940 consequences of that in a non-assert build). Multi-state loops would

3144 fail, whereas previously it would report success if done within two

3327 Avoid dump/reload problems when using both <application>plpython2</>
3328 and <application>plpython3</> (Tom Lane)
3332 In principle, both versions of <application>PL/Python</> can be used in
3333 the same database, though not in the same session (because the two
3334 versions of <application>libpython</> cannot safely be used concurrently).
3335 However, <application>pg_restore</> and <application>pg_upgrade</> both
3336 do things that can fall foul of the same-session restriction. Work

3817 Disable SSL renegotiation by default (Michael Paquier, Andres Freund)
3821 While use of SSL renegotiation is a good idea in theory, we have seen
3822 too many bugs in practice, both in the underlying OpenSSL library and
3823 in our usage of it. Renegotiation will be removed entirely in 9.5 and
3824 later. In the older branches, just change the default value
3825 of <varname>ssl_renegotiation_limit</> to zero (disabled).

4239 These mistakes could lead to incorrect query plans that would give wrong
4240 answers, or to assertion failures in assert-enabled builds, or to odd
4241 planner errors such as <quote>could not devise a query plan for the
4242 given query</>, <quote>could not find pathkey item to
4243 sort</>, <quote>plan should not reference subplan's variable</>,
4244 or <quote>failed to assign all NestLoopParams to plan nodes</>.
4245 Thanks are due to Andreas Seltenreich and Piotr Stefaniak for fuzz
4246 testing that exposed these problems.

4818 Fix <application>pg_dump</> to handle object privileges sanely when
4819 dumping from a server too old to have a particular privilege type
4824 When dumping data types from pre-9.2 servers, and when dumping
4825 functions or procedural languages from pre-7.3
4826 servers, <application>pg_dump</> would
4827 produce <command>GRANT</>/<command>REVOKE</> commands that revoked the
4828 owner's grantable privileges and instead granted all privileges
4829 to <literal>PUBLIC</>. Since the privileges involved are
4830 just <literal>USAGE</> and <literal>EXECUTE</>, this isn't a security
4831 problem, but it's certainly a surprising representation of the older

5161 Fix possible failure to recover from an inconsistent database state
5166 Recent <productname>PostgreSQL</> releases introduced mechanisms to
5167 protect against multixact wraparound, but some of that code did not
5168 account for the possibility that it would need to run during crash
5169 recovery, when the database may not be in a consistent state. This
5170 could result in failure to restart after a crash, or failure to start
5171 up a secondary server. The lingering effects of a previously-fixed
5172 bug in <application>pg_upgrade</> could also cause such a failure, in
5173 installations that had used <application>pg_upgrade</> versions
5174 between 9.3.0 and 9.3.4.
5178 The <application>pg_upgrade</> bug in question was that it would
5179 set <literal>oldestMultiXid</> to 1 in <filename>pg_control</> even
5180 if the true value should be higher. With the fixes introduced in
5181 this release, such a situation will result in immediate emergency
5182 autovacuuming until a correct <literal>oldestMultiXid</> value can
5183 be determined. If that would pose a hardship, users can avoid it by
5184 doing manual vacuuming <emphasis>before</> upgrading to this release.
5190 Check whether <application>pg_controldata</> reports <quote>Latest
5191 checkpoint's oldestMultiXid</> to be 1. If not, there's nothing
5197 Look in <filename>PGDATA/pg_multixact/offsets</> to see if there's a
5198 file named <filename>0000</>. If there is, there's nothing to do.
5203 Otherwise, for each table that has
5204 <structname>pg_class</>.<structfield>relminmxid</> equal to 1,
5205 <command>VACUUM</> that table with
5206 both <xref linkend="guc-vacuum-multixact-freeze-min-age">
5207 and <xref linkend="guc-vacuum-multixact-freeze-table-age"> set to
5208 zero. (You can use the vacuum cost delay parameters described
5209 in <xref linkend="runtime-config-resource-vacuum-cost"> to reduce
5210 the performance consequences for concurrent sessions.)

5229 Fix rare failure to invalidate relation cache init file (Tom Lane)
5233 With just the wrong timing of concurrent activity, a <command>VACUUM
5234 FULL</> on a system catalog might fail to update the <quote>init file</>
5235 that's used to avoid cache-loading work for new sessions. This would
5236 result in later sessions being unable to access that catalog at all.
5237 This is a very ancient bug, but it's so hard to trigger that no
5238 reproducible case had been seen until recently.

5276 Improve planner's cost estimates for semi-joins and anti-joins with
5277 inner indexscans (Tom Lane, Tomas Vondra)
5281 This type of plan is quite cheap when all the join clauses are used
5282 as index scan conditions, even if the inner scan would nominally
5283 fetch many rows, because the executor will stop after obtaining one
5284 row. The planner only partially accounted for that effect, and would
5285 therefore overestimate the cost, leading it to possibly choose some
5286 other much less efficient plan type.

5354 Avoid failures while <function>fsync</>'ing data directory during
5355 crash restart (Abhijit Menon-Sen, Tom Lane)
5359 In the previous minor releases we added a patch to <function>fsync</>
5360 everything in the data directory after a crash. Unfortunately its
5361 response to any error condition was to fail, thereby preventing the
5362 server from starting up, even when the problem was quite harmless.
5363 An example is that an unwritable file in the data directory would
5364 prevent restart on some platforms; but it is common to make SSL
5365 certificate files unwritable by the server. Revise this behavior so
5366 that permissions failures are ignored altogether, and other types of
5367 failures are logged but do not prevent continuing.
5371 Also apply the same rules in <literal>initdb --sync-only</>.
5372 This case is less critical but it should act similarly.

5488 Avoid possible crash when client disconnects just before the
5489 authentication timeout expires (Benkocs Norbert Attila)
5493 If the timeout interrupt fired partway through the session shutdown
5494 sequence, SSL-related state would be freed twice, typically causing a
5495 crash and hence denial of service to other sessions. Experimentation
5496 shows that an unauthenticated remote attacker could trigger the bug
5497 somewhat consistently, hence treat as security issue.

5535 Improve detection of system-call failures (Noah Misch)
5539 Our replacement implementation of <function>snprintf()</> failed to
5540 check for errors reported by the underlying system library calls;
5541 the main case that might be missed is out-of-memory situations.
5542 In the worst case this might lead to information exposure, due to our
5543 code assuming that a buffer had been overwritten when it hadn't been.
5544 Also, there were a few places in which security-relevant calls of other
5545 system library functions did not check for failure.
5549 It remains possible that some calls of the <function>*printf()</>
5550 family of functions are vulnerable to information disclosure if an
5551 out-of-memory error occurs at just the wrong time. We judge the risk
5552 to not be large, but will continue analysis in this area.

5569 In <filename>contrib/pgcrypto</>, uniformly report decryption failures
5570 as <quote>Wrong key or corrupt data</> (Noah Misch)
5574 Previously, some cases of decryption with an incorrect key could report
5575 other error message texts. It has been shown that such variance in
5576 error reports can aid attackers in recovering keys from other systems.
5577 While it's unknown whether <filename>pgcrypto</>'s specific behaviors
5578 are likewise exploitable, it seems better to avoid the risk by using a
5579 one-size-fits-all message.

5621 Protect against wraparound of multixact member IDs
5622 (Álvaro Herrera, Robert Haas, Thomas Munro)
5626 Under certain usage patterns, the existing defenses against this might
5627 be insufficient, allowing <filename>pg_multixact/members</> files to be
5628 removed too early, resulting in data loss.
5629 The fix for this includes modifying the server to fail transactions
5630 that would result in overwriting old multixact member ID data, and
5631 improving autovacuum to ensure it will act proactively to prevent
5632 multixact member ID wraparound, as it does for transaction ID

5648 Fix incorrect declaration of <filename>contrib/citext</>'s
5649 <function>regexp_matches()</> functions (Tom Lane)
5653 These functions should return <type>setof text[]</>, like the core
5654 functions they are wrappers for; but they were incorrectly declared as
5655 returning just <type>text[]</>. This mistake had two results: first,
5656 if there was no match you got a scalar null result, whereas what you
5657 should get is an empty set (zero rows). Second, the <literal>g</> flag
5658 was effectively ignored, since you would get only one result array even
5659 if there were multiple matches.
5663 While the latter behavior is clearly a bug, there might be applications
5664 depending on the former behavior; therefore the function declarations
5665 will not be changed by default until <productname>PostgreSQL</> 9.5.
5666 In pre-9.5 branches, the old behavior exists in version 1.0 of
5667 the <literal>citext</> extension, while we have provided corrected
5668 declarations in version 1.1 (which is <emphasis>not</> installed by
5669 default). To adopt the fix in pre-9.5 branches, execute
5670 <literal>ALTER EXTENSION citext UPDATE TO '1.1'</> in each database in
5671 which <literal>citext</> is installed. (You can also <quote>update</>
5672 back to 1.0 if you need to undo that.) Be aware that either update
5673 direction will require dropping and recreating any views or rules that
5674 use <filename>citext</>'s <function>regexp_matches()</> functions.

5760 Fix planning of star-schema-style queries (Tom Lane)
5764 Sometimes, efficient scanning of a large table requires that index
5765 parameters be provided from more than one other table (commonly,
5766 dimension tables whose keys are needed to index a large fact table).
5767 The planner should be able to find such plans, but an overly
5768 restrictive search heuristic prevented it.

5813 Previously, if textually identical non-strict subexpressions were used
5814 both above and below an outer join, the planner might try to re-use
5815 the value computed below the join, which would be incorrect because the
5816 executor would force the value to NULL in case of an unmatched outer row.

6227 Remove code for matching IPv4 <filename>pg_hba.conf</> entries to
6228 IPv4-in-IPv6 addresses (Tom Lane)
6232 This hack was added in 2003 in response to a report that some Linux
6233 kernels of the time would report IPv4 connections as having
6234 IPv4-in-IPv6 addresses. However, the logic was accidentally broken in
6235 9.0. The lack of any field complaints since then shows that it's not
6236 needed anymore. Now we have reports that the broken code causes
6237 crashes on some systems, so let's just remove it rather than fix it.
6238 (Had we chosen to fix it, that would make for a subtle and potentially
6239 security-sensitive change in the effective meaning of
6240 IPv4 <filename>pg_hba.conf</> entries, which does not seem like a good
6241 thing to do in minor releases.)

6323 Reduce risk of network deadlock when using <application>libpq</>'s
6324 non-blocking mode (Heikki Linnakangas)
6328 When sending large volumes of data, it's important to drain the input
6329 buffer every so often, in case the server has sent enough response data
6330 to cause it to block on output. (A typical scenario is that the server
6331 is sending a stream of NOTICE messages during <literal>COPY FROM
6332 STDIN</>.) This worked properly in the normal blocking mode, but not
6333 so much in non-blocking mode. We've modified <application>libpq</>
6334 to opportunistically drain input when it can, but a full defense
6335 against this problem requires application cooperation: the application
6336 should watch for socket read-ready as well as write-ready conditions,
6337 and be sure to call <function>PQconsumeInput()</> upon read-ready.

6780 When <function>to_char()</> processes a numeric formatting template
6781 calling for a large number of digits, <productname>PostgreSQL</>
6782 would read past the end of a buffer. When processing a crafted

6803 Fix buffer overrun in replacement <function>*printf()</> functions
6808 <productname>PostgreSQL</> includes a replacement implementation
6809 of <function>printf</> and related functions. This code will overrun
6810 a stack buffer when formatting a floating point number (conversion
6811 specifiers <literal>e</>, <literal>E</>, <literal>f</>, <literal>F</>,
6812 <literal>g</> or <literal>G</>) with requested precision greater than
6813 about 500. This will crash the server, and we have not ruled out the
6814 possibility of attacks that lead to privilege escalation.
6815 A database user can trigger such a buffer overrun through
6816 the <function>to_char()</> SQL function. While that is the only
6817 affected core <productname>PostgreSQL</> functionality, extension
6818 modules that use printf-family functions may be at risk as well.
6822 This issue primarily affects <productname>PostgreSQL</> on Windows.
6823 <productname>PostgreSQL</> uses the system implementation of these
6824 functions where adequate, which it is on other modern platforms.

6874 Fix possible loss of frontend/backend protocol synchronization after
6876 (Heikki Linnakangas)
6880 If any error occurred while the server was in the middle of reading a
6881 protocol message from the client, it could lose synchronization and
6882 incorrectly try to interpret part of the message's data as a new
6883 protocol message. An attacker able to submit crafted binary data
6884 within a command parameter might succeed in injecting his own SQL
6885 commands this way. Statement timeout and query cancellation are the
6886 most likely sources of errors triggering this scenario. Particularly
6887 vulnerable are applications that use a timeout and also submit
6888 arbitrary user-crafted data as binary query parameters. Disabling
6889 statement timeout will reduce, but not eliminate, the risk of
6890 exploit. Our thanks to Emil Lenngren for reporting this issue.

6907 Fix information leak via constraint-violation error messages
6912 Some server error messages show the values of columns that violate
6913 a constraint, such as a unique constraint. If the user does not have
6914 <literal>SELECT</> privilege on all columns of the table, this could
6915 mean exposing values that the user should not be able to see. Adjust
6916 the code so that values are displayed only when they came from the SQL
6917 command or could be selected by the user.

6963 Cope with the Windows locale named <quote>Norwegian (Bokmål)</>
6964 (Heikki Linnakangas)
6968 Non-ASCII locale names are problematic since it's not clear what
6969 encoding they should be represented in. Map the troublesome locale
6970 name to a plain-ASCII alias, <quote>Norwegian_Norway</>.
6974 9.4.0 mapped the troublesome name to <quote>norwegian-bokmal</>,
6975 but that turns out not to work on all Windows configurations.
6976 <quote>Norwegian_Norway</> is now recommended instead.

7053 Fix <type>jsonb</> Unicode escape processing, and in consequence
7054 disallow <literal>\u0000</> (Tom Lane)
7058 Previously, the JSON Unicode escape <literal>\u0000</> was accepted
7059 and was stored as those six characters; but that is indistinguishable
7060 from what is stored for the input <literal>\\u0000</>, resulting in
7061 ambiguity. Moreover, in cases where de-escaped textual output is
7062 expected, such as the <literal>->></> operator, the sequence was
7063 printed as <literal>\u0000</>, which does not meet the expectation
7064 that JSON escaping would be removed. (Consistent behavior would
7065 require emitting a zero byte, but <productname>PostgreSQL</> does not
7066 support zero bytes embedded in text strings.) 9.4.0 included an
7067 ill-advised attempt to improve this situation by adjusting JSON output
7068 conversion rules; but of course that could not fix the fundamental
7069 ambiguity, and it turned out to break other usages of Unicode escape
7070 sequences. Revert that, and to avoid the core problem,
7071 reject <literal>\u0000</> in <type>jsonb</> input.
7075 If a <type>jsonb</> column contains a <literal>\u0000</> value stored
7076 with 9.4.0, it will henceforth read out as though it
7077 were <literal>\\u0000</>, which is the other valid interpretation of
7078 the data stored by 9.4.0 for this case.
7082 The <type>json</> type did not have the storage-ambiguity problem, but
7083 it did have the problem of inconsistent de-escaped textual output.
7084 Therefore <literal>\u0000</> will now also be rejected
7085 in <type>json</> values when conversion to de-escaped form is
7086 required. This change does not break the ability to
7087 store <literal>\u0000</> in <type>json</> columns so long as no
7088 processing is done on the values. This is exactly parallel to the
7089 cases in which non-ASCII Unicode escapes are allowed when the database
7090 encoding is not UTF8.

7106 Fix namespace handling in <function>xpath()</> (Ali Akbar)
7110 Previously, the <type>xml</> value resulting from
7111 an <function>xpath()</> call would not have namespace declarations if
7112 the namespace declarations were attached to an ancestor element in the
7113 input <type>xml</> value, rather than to the specific element being
7114 returned. Propagate the ancestral declaration so that the result is
7115 correct when considered in isolation.

7462 Allow <varname>CFLAGS</> from <application>configure</>'s environment
7463 to override automatically-supplied <varname>CFLAGS</> (Tom Lane)
7467 Previously, <application>configure</> would add any switches that it
7468 chose of its own accord to the end of the
7469 user-specified <varname>CFLAGS</> string. Since most compilers
7470 process switches left-to-right, this meant that configure's choices
7471 would override the user-specified flags in case of conflicts. That
7472 should work the other way around, so adjust the logic to put the
7473 user's string at the end not the beginning.

7544 Major enhancements in <productname>PostgreSQL</> 9.4 include:
7547 <!-- This list duplicates items below, but without authors or details-->
7553 Add <link linkend="datatype-json"><type>jsonb</></link>, a more
7554 capable and efficient data type for storing <acronym>JSON</> data
7560 Add new <acronym>SQL</> command <xref linkend="SQL-ALTERSYSTEM">
7561 for changing <filename>postgresql.conf</> configuration file entries
7567 Reduce lock strength for some <xref linkend="SQL-ALTERTABLE">
7574 Allow <link linkend="rules-materializedviews">materialized views</>
7575 to be refreshed without blocking concurrent reads

7590 to be dynamically registered, started and terminated
7597 The above items are explained in more detail in the sections below.
7604 <title>Migration to Version 9.4</title>
7607 A dump/restore using <xref linkend="app-pg-dumpall">, or use
7608 of <xref linkend="pgupgrade">, is required for those wishing to migrate
7609 data from any previous release.
7613 Version 9.4 contains a number of changes that may affect compatibility
7614 with previous releases. Observe the following incompatibilities:
7621 Tighten checks for multidimensional <link
7622 linkend="arrays">array</link> input (Bruce Momjian)
7626 Previously, an input array string that started with a single-element
7627 sub-array could later contain multi-element sub-arrays,
7628 e.g. <literal>'{{1}, {2,3}}'::int[]</> would be accepted.
7634 When converting values of type <type>date</>, <type>timestamp</>
7635 or <type>timestamptz</>
7636 to <link linkend="datatype-json"><type>JSON</type></link>, render the
7637 values in a format compliant with ISO 8601 (Andrew Dunstan)
7641 Previously such values were rendered according to the current
7642 <xref linkend="guc-datestyle"> setting; but many JSON processors
7643 require timestamps to be in ISO 8601 format. If necessary, the
7644 previous behavior can be obtained by explicitly casting the datetime
7645 value to <type>text</> before passing it to the JSON conversion
7652 The <link linkend="functions-json-op-table"><type>json</type>
7653 <literal>#></> <type>text[]</></link> path extraction operator now
7654 returns its lefthand input, not NULL, if the array is empty (Tom Lane)
7658 This is consistent with the notion that this represents zero
7659 applications of the simple field/element extraction
7660 operator <literal>-></>. Similarly, <type>json</type>
7661 <literal>#>></> <type>text[]</> with an empty array merely
7662 coerces its lefthand input to text.
7669 the <link linkend="functions-json-op-table"><type>JSON</type>
7670 field/element/path extraction operators</link> now return NULL rather
7671 than raising an error (Tom Lane)
7675 For example, applying field extraction to a JSON array now yields NULL
7676 not an error. This is more consistent (since some comparable cases such
7677 as no-such-field already returned NULL), and it makes it safe to create
7678 expression indexes that use these operators, since they will now not
7679 throw errors for any valid JSON input.
7685 Cause consecutive whitespace in <link
7686 linkend="functions-formatting-table"><function>to_timestamp()</></link>
7687 and <function>to_date()</> format strings to consume a corresponding
7688 number of characters in the input string (whitespace or not), then
7689 conditionally consume adjacent whitespace, if not in <literal>FX</>
7690 mode (Jeevan Chalke)
7694 Previously, consecutive whitespace characters in a non-<literal>FX</>
7695 format string behaved like a single whitespace character and consumed
7696 all adjacent whitespace in the input string. For example, previously
7697 a format string of three spaces would consume only the first space in
7698 <literal>' 12'</>, but it will now consume all three characters.
7705 linkend="textsearch-functions-table"><function>ts_rank_cd()</></link>
7706 to ignore stripped lexemes (Alex Hill)
7710 Previously, stripped lexemes were treated as if they had a default
7711 location, producing a rank of dubious usefulness.
7717 For functions declared to
7718 take <link linkend="xfunc-sql-variadic-functions"><literal>VARIADIC
7719 "any"</></link>, an actual parameter marked as <literal>VARIADIC</>
7720 must be of a determinable array type (Pavel Stehule)
7724 Such parameters can no longer be written as an undecorated string
7725 literal or <literal>NULL</>; a cast to an appropriate array data type
7726 will now be required. Note that this does not affect parameters not
7727 marked <literal>VARIADIC</>.
7733 Ensure that whole-row variables expose the expected column names
7734 to functions that pay attention to column names within composite
7735 arguments (Tom Lane)
7739 Constructs like <literal>row_to_json(tab.*)</> now always emit column
7740 names that match the column aliases visible for table <literal>tab</>
7741 at the point of the call. In previous releases the emitted column
7742 names would sometimes be the table's actual column names regardless
7743 of any aliases assigned in the query.
7749 <xref linkend="sql-discard"> now also discards sequence-related state
7750 (Fabrízio de Royes Mello, Robert Haas)
7756 Rename <link linkend="SQL-EXPLAIN"><command>EXPLAIN
7757 ANALYZE</></link>'s <quote>total runtime</quote> output
7758 to <quote>execution time</quote> (Tom Lane)
7762 Now that planning time is also reported, the previous name was
7769 <link linkend="SQL-SHOW"><command>SHOW TIME ZONE</></link> now
7770 outputs simple numeric UTC offsets in <acronym>POSIX</> timezone
7775 Previously, such timezone settings were displayed as <link
7776 linkend="datatype-interval-output"><type>interval</></link> values.
7777 The new output is properly interpreted by <command>SET TIME ZONE</>
7778 when passed as a simple string, whereas the old output required
7779 special treatment to be re-parsed correctly.
7785 Foreign data wrappers that support updating foreign tables must
7786 consider the possible presence of <literal>AFTER ROW</> triggers
7791 When an <literal>AFTER ROW</> trigger is present, all columns of the
7792 table must be returned by updating actions, since the trigger might
7793 inspect any or all of them. Previously, foreign tables never had
7794 triggers, so the FDW might optimize away fetching columns not mentioned
7795 in the <literal>RETURNING</> clause (if any).
7802 linkend="ddl-constraints-check-constraints"><literal>CHECK</></link>
7803 constraints from referencing system columns, except
7804 <structfield>tableoid</> (Amit Kapila)
7808 Previously such check constraints were allowed, but they would often
7809 cause errors during restores.
7815 Use the last specified <link linkend="recovery-target-settings">recovery
7816 target parameter</link> if multiple target parameters are specified
7817 (Heikki Linnakangas)
7821 Previously, there was an undocumented precedence order among
7822 the <literal>recovery_target_<replaceable>xxx</></literal> parameters.
7828 On Windows, automatically preserve quotes in command strings supplied
7829 by the user (Heikki Linnakangas)
7833 User commands that did their own quote preservation might need
7834 adjustment. This is likely to be an issue for commands used in
7835 <xref linkend="guc-archive-command">, <xref linkend="restore-command">,
7836 and <link linkend="sql-copy"><command>COPY TO/FROM PROGRAM</></link>.
7842 Remove catalog column <link
7843 linkend="catalog-pg-class"><structfield>pg_class.reltoastidxid</></link>
7850 Remove catalog column <link
7851 linkend="catalog-pg-rewrite"><structfield>pg_rewrite.ev_attr</></link>
7856 Per-column rules have not been supported since
7857 <application>PostgreSQL</> 7.3.
7863 Remove native support for <application>Kerberos</> authentication
7864 (<option>--with-krb5</>, etc)
7869 The supported way to use <application>Kerberos</> authentication is
7870 with <acronym>GSSAPI</>. The native code has been deprecated since
7871 <productname>PostgreSQL</> 8.3.
7877 In <application>PL/Python</>, handle domains over arrays like the
7878 underlying array type (Rodolfo Campero)
7882 Previously such values were treated as strings.
7889 linkend="libpq-pqconnectdbparams"><function>PQconnectdbParams()</></link>
7891 linkend="libpq-pqpingparams"><function>PQpingParams()</></link>
7892 functions process zero-length strings as defaults (Adrian
7897 Previously, these functions treated zero-length string values as
7898 selecting the default in only some cases.
7904 Change empty arrays returned by the <xref linkend="intarray"> module
7905 to be zero-dimensional arrays (Bruce Momjian)
7909 Previously, empty arrays were returned as zero-length one-dimensional
7910 arrays, whose text representation looked the same as zero-dimensional
7911 arrays (<literal>{}</>), but they acted differently in array
7912 operations. <application>intarray</>'s behavior in this area now
7913 matches the built-in array operators.
7919 <xref linkend="pgupgrade"> now uses <option>-U</>
7920 or <option>--username</> to specify the user name (Bruce Momjian)
7924 Previously this option was spelled <option>-u</> or <option>--user</>,
7925 but that was inconsistent with other tools.
7934 <title>Changes</title>
7937 Below you will find a detailed account of the changes between
7938 <productname>PostgreSQL</productname> 9.4 and the previous major
7943 <title>Server</title>
7949 Allow <link linkend="bgworker">background worker processes</link>
7950 to be dynamically registered, started and terminated (Robert Haas)
7954 The new <filename>worker_spi</> module shows an example of use
7961 Allow dynamic allocation of shared memory segments (Robert Haas,
7966 This feature is illustrated in the <filename>test_shm_mq</filename>
7973 During crash recovery or immediate shutdown, send uncatchable
7974 termination signals (<systemitem>SIGKILL</>) to child processes
7975 that do not shut down promptly (MauMau, Álvaro Herrera)
7979 This reduces the likelihood of leaving orphaned child processes
7980 behind after <xref linkend="app-postmaster"> shutdown, as well
7981 as ensuring that crash recovery can proceed if some child processes
7982 have become <quote>stuck</>.
7988 Improve randomness of the database system identifier (Tom Lane)
7994 Make <xref linkend="SQL-VACUUM"> properly report dead but
7995 not-yet-removable rows to the statistics collector (Hari Babu)
7999 Previously these were reported as live rows.
8006 <title>Indexes</title>
8012 Reduce <link linkend="GIN"><acronym>GIN</></link> index size
8013 (Alexander Korotkov, Heikki Linnakangas)
8017 Indexes upgraded via <xref linkend="pgupgrade"> will work fine
8018 but will still be in the old, larger <acronym>GIN</> format.
8019 Use <xref linkend="SQL-REINDEX"> to recreate old GIN indexes in the
8026 Improve speed of multi-key <link
8027 linkend="GIN"><acronym>GIN</></link> lookups (Alexander Korotkov,
8034 Add <link linkend="GiST"><acronym>GiST</></link> index support
8035 for <link linkend="datatype-inet"><type>inet</></link> and
8036 <link linkend="datatype-cidr"><type>cidr</></link> data types
8041 Such indexes improve <link
8042 linkend="cidr-inet-operators-table">subnet and supernet</link>
8043 lookups and ordering comparisons.
8049 Fix rare race condition in B-tree page deletion (Heikki Linnakangas)
8055 Make the handling of interrupted B-tree page splits more robust
8056 (Heikki Linnakangas)
8065 <title>General Performance</title>
8071 Allow multiple backends to insert
8072 into <link linkend="wal"><acronym>WAL</></link> buffers
8073 concurrently (Heikki Linnakangas)
8077 This improves parallel write performance.
8083 Conditionally write only the modified portion of updated rows to
8084 <link linkend="wal"><acronym>WAL</></link> (Amit Kapila)
8090 Improve performance of aggregate functions used as <link
8091 linkend="syntax-window-functions">window functions</link>
8092 (David Rowley, Florian Pflug, Tom Lane)
8098 Improve speed of aggregates that
8099 use <link linkend="datatype-numeric"><type>numeric</></link> state
8100 values (Hadi Moshayedi)
8106 Attempt to <link linkend="vacuum-for-wraparound">freeze</link>
8107 tuples when tables are rewritten with <xref
8108 linkend="SQL-CLUSTER"> or <link
8109 linkend="SQL-VACUUM"><command>VACUUM FULL</></link> (Robert Haas,
8114 This can avoid the need to freeze the tuples in the future.
8120 Improve speed of <xref linkend="SQL-COPY"> with default <link
8121 linkend="functions-sequence-table"><function>nextval()</></link>
8122 columns (Simon Riggs)
8128 Improve speed of accessing many different <link
8129 linkend="SQL-CREATESEQUENCE">sequences</link> in the same session
8136 Raise hard limit on the number of tuples held in memory during sorting
8137 and B-tree index builds (Noah Misch)
8143 Reduce memory allocated by <application>PL/pgSQL</>
8144 <xref linkend="SQL-DO"> blocks (Tom Lane)
8150 Make the planner more aggressive about extracting restriction clauses
8151 from mixed <literal>AND</>/<literal>OR</> clauses (Tom Lane)
8157 Disallow pushing volatile <literal>WHERE</> clauses down
8158 into <literal>DISTINCT</> subqueries (Tom Lane)
8162 Pushing down a <literal>WHERE</> clause can produce a more
8163 efficient plan overall, but at the cost of evaluating the clause
8164 more often than is implied by the text of the query; so don't do it
8165 if the clause contains any volatile functions.
8171 Auto-resize the catalog caches (Heikki Linnakangas)
8175 This reduces memory consumption for sessions accessing only a few
8176 tables, and improves performance for sessions accessing many tables.
8185 <title>Monitoring</title>
8191 Add <xref linkend="pg-stat-archiver-view"> system view to
8192 report <link linkend="wal"><acronym>WAL</></link> archiver activity
8193 (Gabriele Bartolini)
8199 Add <structfield>n_mod_since_analyze</> columns to
8200 <xref linkend="pg-stat-all-tables-view"> and related system views
8205 These columns expose the system's estimate of the number of changed
8206 tuples since the table's last <xref linkend="sql-analyze">. This
8207 estimate drives decisions about when to auto-analyze.
8213 Add <structfield>backend_xid</> and <structfield>backend_xmin</>
8214 columns to the system view <xref linkend="pg-stat-activity-view">,
8215 and a <structfield>backend_xmin</> column to
8216 <xref linkend="pg-stat-replication-view"> (Christian Kruse)
8225 <title><acronym>SSL</></title>
8231 Add support for <acronym>SSL</> <acronym>ECDH</> key exchange
8236 This allows use of Elliptic Curve keys for server authentication.
8237 Such keys are faster and have better security than <acronym>RSA</>
8238 keys. The new configuration parameter
8239 <xref linkend="guc-ssl-ecdh-curve">
8240 controls which curve is used for <acronym>ECDH</>.
8246 Improve the default <xref linkend="guc-ssl-ciphers"> setting
8253 By default, the server not the client now controls the preference
8254 order of <acronym>SSL</> ciphers
8259 Previously, the order specified by <xref linkend="guc-ssl-ciphers">
8260 was usually ignored in favor of client-side defaults, which are not
8261 configurable in most <productname>PostgreSQL</> clients. If
8262 desired, the old behavior can be restored via the new configuration
8263 parameter <xref linkend="guc-ssl-prefer-server-ciphers">.
8269 Make <xref linkend="guc-log-connections"> show <acronym>SSL</>
8270 encryption information (Andreas Kunert)
8276 Improve <acronym>SSL</> renegotiation handling (Álvaro
8286 <title>Server Settings</title>
8292 Add new <acronym>SQL</> command <xref linkend="SQL-ALTERSYSTEM">
8293 for changing <filename>postgresql.conf</> configuration file entries
8298 Previously such settings could only be changed by manually
8299 editing <filename>postgresql.conf</>.
8305 Add <xref linkend="guc-autovacuum-work-mem"> configuration parameter
8306 to control the amount of memory used by autovacuum workers
8313 Add <xref linkend="guc-huge-pages"> parameter to allow using huge
8314 memory pages on Linux (Christian Kruse, Richard Poole, Abhijit
8319 This can improve performance on large-memory systems.
8325 Add <xref linkend="guc-max-worker-processes"> parameter
8326 to limit the number of background workers (Robert Haas)
8330 This is helpful in configuring a standby server to have the
8331 required number of worker processes (the same as the primary).
8337 Add superuser-only <xref linkend="guc-session-preload-libraries">
8338 parameter to load libraries at session start (Peter Eisentraut)
8342 In contrast to <xref linkend="guc-local-preload-libraries">, this
8343 parameter can load any shared library, not just those in
8344 the <filename>$libdir/plugins</> directory.
8350 Add <xref linkend="guc-wal-log-hints"> parameter to enable WAL
8351 logging of hint-bit changes (Sawada Masahiko)
8355 Hint bit changes are not normally logged, except when checksums are
8356 enabled. This is useful for external tools
8357 like <application>pg_rewind</>.
8363 Increase the default settings of <xref linkend="guc-work-mem">
8364 and <xref linkend="guc-maintenance-work-mem"> by four times (Bruce
8369 The new defaults are 4MB and 64MB respectively.
8375 Increase the default setting of <xref
8376 linkend="guc-effective-cache-size">
8377 to 4GB (Bruce Momjian, Tom Lane)
8383 Allow <function>printf</function>-style space padding to be
8384 specified in <xref linkend="guc-log-line-prefix"> (David Rowley)
8390 Allow terabyte units (<literal>TB</>) to be used when specifying
8391 configuration variable values (Simon Riggs)
8397 Show <acronym>PID</>s of lock holders and waiters and improve
8398 information about relations in <xref linkend="guc-log-lock-waits">
8399 log messages (Christian Kruse)
8405 Reduce server logging level when loading shared libraries (Peter
8410 The previous level was <literal>LOG</>, which was too verbose
8411 for libraries loaded per-session.
8417 On Windows, make <literal>SQL_ASCII</>-encoded databases and server
8418 processes (e.g., <xref linkend="app-postmaster">) emit messages in
8419 the character encoding of the server's Windows user locale
8420 (Alexander Law, Noah Misch)
8424 Previously these messages were output in the Windows
8425 <acronym>ANSI</> code page.
8436 <title>Replication and Recovery</title>
8442 Add <link linkend="streaming-replication-slots">replication
8443 slots</link> to coordinate activity on streaming standbys with the
8444 node they are streaming from (Andres Freund, Robert Haas)
8448 Replication slots allow preservation of resources like
8449 <acronym>WAL</> files on the primary until they are no longer
8450 needed by standby servers.
8456 Add recovery parameter <xref linkend="recovery-min-apply-delay">
8457 to delay replication (Robert Haas, Fabrízio de Royes Mello,
8462 Delaying replay on standby servers can be useful for recovering
8469 Add <xref linkend="recovery-target">
8470 option <option>immediate</> to stop <link
8471 linkend="wal"><acronym>WAL</></link> recovery as soon as a
8472 consistent state is reached (MauMau, Heikki Linnakangas)
8478 Improve recovery target processing (Heikki Linnakangas)
8482 The timestamp reported
8483 by <link linkend="functions-recovery-info-table"><function>pg_last_xact_replay_timestamp()</></link>
8484 now reflects already-committed records, not transactions about to
8485 be committed. Recovering to a restore point now replays the restore
8486 point, rather than stopping just before the restore point.
8493 linkend="functions-admin-backup-table"><function>pg_switch_xlog()</></link>
8494 now clears any unused trailing space in the old <acronym>WAL</> file
8495 (Heikki Linnakangas)
8499 This improves the compression ratio for <acronym>WAL</> files.
8505 Report failure return codes from <link
8506 linkend="archive-recovery-settings">external recovery commands</>
8513 Reduce spinlock contention during <acronym>WAL</> replay (Heikki
8520 Write <acronym>WAL</> records of running transactions more
8521 frequently (Andres Freund)
8525 This allows standby servers to start faster and clean up resources
8533 <title><link linkend="logicaldecoding">Logical Decoding</></title>
8536 Logical decoding allows database changes to be streamed in a
8537 configurable format. The data is read from
8538 the <link linkend="wal"><acronym>WAL</></link> and transformed into the
8539 desired target format. To implement this feature, the following changes
8547 Add support for <link linkend="logicaldecoding">logical decoding</>
8548 of WAL data, to allow database changes to be streamed out in a
8556 Add new <xref linkend="guc-wal-level"> setting <option>logical</>
8557 to enable logical change-set encoding in <acronym>WAL</> (Andres
8564 Add table-level parameter <link
8565 linkend="catalog-pg-class"><literal>REPLICA IDENTITY</></link>
8566 to control logical replication (Andres Freund)
8572 Add relation option <link
8573 linkend="SQL-CREATETABLE-storage-parameters"><option>user_catalog_table</></link>
8574 to identify user-created tables involved in logical change-set
8575 encoding (Andres Freund)
8581 Add <xref linkend="app-pgrecvlogical"> application to receive
8582 logical-decoding data (Andres Freund)
8588 Add <xref linkend="test-decoding"> module to illustrate logical
8589 decoding at the <acronym>SQL</> level (Andres Freund)
8600 <title>Queries</title>
8606 Add <link linkend="queries-tablefunctions"><literal>WITH
8607 ORDINALITY</></link> syntax to number the rows returned from a
8608 set-returning function in the <literal>FROM</> clause
8609 (Andrew Gierth, David Fetter)
8613 This is particularly useful for functions like
8614 <function>unnest()</>.
8620 Add <link linkend="queries-tablefunctions"><literal>ROWS
8621 FROM()</></link> syntax to allow horizontal concatenation of
8622 set-returning functions in the <literal>FROM</> clause (Andrew Gierth)
8628 Allow <xref linkend="SQL-SELECT"> to have
8629 an empty target list (Tom Lane)
8633 This was added so that views that select from a table with zero
8634 columns can be dumped and restored correctly.
8640 Ensure that <link linkend="SQL-SELECT"><literal>SELECT ... FOR UPDATE
8641 NOWAIT</></link> does not wait in corner cases involving
8642 already-concurrently-updated tuples (Craig Ringer and Thomas Munro)
8651 <title>Utility Commands</title>
8657 Add <link linkend="SQL-DISCARD"><command>DISCARD
8658 SEQUENCES</></link> command to discard cached sequence-related state
8659 (Fabrízio de Royes Mello, Robert Haas)
8663 <command>DISCARD ALL</> will now also discard such information.
8669 Add <literal>FORCE NULL</> option
8670 to <link linkend="SQL-COPY"><command>COPY FROM</></link>, which
8671 causes quoted strings matching the specified null string to be
8672 converted to NULLs in <literal>CSV</> mode (Ian Barwick, Michael
8677 Without this option, only unquoted matching strings will be imported
8684 Issue warnings for commands used outside of transaction blocks
8685 when they can have no effect (Bruce Momjian)
8689 New warnings are issued for <command>SET

8755 Previously the presence of non-updatable output columns such as
8756 expressions, literals, and function calls prevented automatic
8757 updates. Now <command>INSERT</>s, <command>UPDATE</>s and
8758 <command>DELETE</>s are supported, provided that they do not
8759 attempt to assign new values to any of the non-updatable columns.
8765 Allow control over whether <command>INSERT</>s and
8766 <command>UPDATE</>s can add rows to an auto-updatable view that
8767 would not appear in the view (Dean Rasheed)
8771 This is controlled with the new <xref linkend="SQL-CREATEVIEW">

8895 The line <emphasis>segment</> data type (<link

8897 fully supported. The previous <type>line</> data type (which was
8898 enabled only via a compile-time option) is not binary or
8899 dump-compatible with the new implementation.
8905 Add <link linkend="datatype-pg-lsn"><type>pg_lsn</></link>
8906 data type to represent a <acronym>WAL</> log sequence number
8907 (<acronym>LSN</>) (Robert Haas, Michael Paquier)
8913 Allow single-point <link
8914 linkend="datatype-polygon"><type>polygon</></link>s to be converted
8915 to <link linkend="datatype-circle"><type>circle</></link>s
8922 Support time zone abbreviations that change UTC offset from time to
8927 Previously, <productname>PostgreSQL</> assumed that the UTC offset
8928 associated with a time zone abbreviation (such as <literal>EST</>)
8929 never changes in the usage of any particular locale. However this
8930 assumption fails in the real world, so introduce the ability for a
8931 zone abbreviation to represent a UTC offset that sometimes changes.
8932 Update the zone abbreviation definition files to make use of this
8933 feature in timezone locales that have changed the UTC offset of their
8934 abbreviations since 1970 (according to the IANA timezone database).
8935 In such timezones, <productname>PostgreSQL</> will now associate the
8936 correct UTC offset with the abbreviation depending on the given date.
8942 Allow 5+ digit years for non-<acronym>ISO</> <link

8967 (Oleg Bartunov, Teodor Sigaev, Alexander
8968 Korotkov, Peter Geoghegan, Andrew Dunstan)
8972 This new type allows faster access to values within a JSON
8973 document, and faster and more useful indexing of JSON columns.
8974 Scalar values in <type>jsonb</> documents are stored as appropriate
8975 scalar SQL types, and the JSON document structure is pre-parsed
8976 rather than being stored as text as in the original <type>json</>
8983 Add new JSON functions to allow for the construction
8984 of arbitrarily complex JSON trees (Andrew Dunstan, Laurence Rowe)
8988 New functions include <link

9024 The existing <function>pg_sleep()</> function only supports delays
9025 specified in seconds.
9032 linkend="array-functions-table"><function>cardinality()</></link>
9033 function for arrays (Marko Tiikkaja)
9037 This returns the total number of elements in the array, or zero

9044 Add <acronym>SQL</> functions to allow <link linkend="lo-funcs">large
9045 object reads/writes</link> at arbitrary offsets (Pavel Stehule)
9052 linkend="array-functions-table"><function>unnest()</></link>
9053 to take multiple arguments, which are individually unnested then
9054 horizontally concatenated (Andrew Gierth)
9060 Add functions to construct <type>time</>s, <type>date</>s,
9061 <type>timestamp</>s, <type>timestamptz</>s, and <type>interval</>s
9062 from individual values, rather than strings (Pavel Stehule)
9066 These functions' names are prefixed with <literal>make_</>,
9067 e.g. <link linkend="functions-datetime-table"><function>make_date()</></link>.

9136 non-existent object instead of failing.
9143 linkend="functions-admin-dblocation"><function>pg_filenode_relation()</></link>
9144 to allow for more efficient lookup of relation names from filenodes

10057 Allow reporting of <application>pg_stat_statements</>'s internal
10058 query hash identifier (Daniel Farina, Sameer Thakur, Peter
10065 Add the ability to retrieve all <application>pg_stat_statements</>
10066 information except the query text (Peter Geoghegan)
10070 This allows monitoring tools to fetch query text only for
10071 just-created entries, improving performance during repeated querying
10078 Make <application>pg_stat_statements</> ignore <command>DEALLOCATE</>
10079 commands (Fabien Coelho)

10091 shutdown, rather than <filename>$PGDATA/global</> (Fujii Masao)
