8 <title>Release Date</title>
9 <simpara>2016-02-11</simpara>
13 This release contains a variety of fixes from 9.3.10.
14 For information about new features in the 9.3 major release, see
15 <xref linkend="release-9-3">.
19 <title>Migration to Version 9.3.11</title>
22 A dump/restore is not required for those running 9.3.X.
26 However, if you are upgrading from a version earlier than 9.3.9,
27 see <xref linkend="release-9-3-9">.
33 <title>Changes</title>
39 Perform an immediate shutdown if the <filename>postmaster.pid</> file
44 The postmaster now checks every minute or so
45 that <filename>postmaster.pid</> is still there and still contains its
46 own PID. If not, it performs an immediate shutdown, as though it had
47 received <systemitem>SIGQUIT</>. The main motivation for this change
48 is to ensure that failed buildfarm runs will get cleaned up without
49 manual intervention; but it also serves to limit the bad effects if a
50 DBA forcibly removes <filename>postmaster.pid</> and then starts a new
57 In <literal>SERIALIZABLE</> transaction isolation mode, serialization
58 anomalies could be missed due to race conditions during insertions
59 (Kevin Grittner, Thomas Munro)
65 Fix failure to emit appropriate WAL records when doing <literal>ALTER
66 TABLE ... SET TABLESPACE</> for unlogged relations (Michael Paquier,
71 Even though the relation's data is unlogged, the move must be logged or
72 the relation will be inaccessible after a standby is promoted to master.
78 Fix possible misinitialization of unlogged relations at the end of
79 crash recovery (Andres Freund, Michael Paquier)
85 Ensure walsender slots are fully re-initialized when being re-used
92 Fix <command>ALTER COLUMN TYPE</> to reconstruct inherited check
93 constraints properly (Tom Lane)
99 Fix <command>REASSIGN OWNED</> to change ownership of composite types
100 properly (Álvaro Herrera)
106 Fix <command>REASSIGN OWNED</> and <command>ALTER OWNER</> to correctly
107 update granted-permissions lists when changing owners of data types,
108 foreign data wrappers, or foreign servers (Bruce Momjian,
109 Álvaro Herrera)
115 Fix <command>REASSIGN OWNED</> to ignore foreign user mappings,
116 rather than fail (Álvaro Herrera)
122 Fix possible crash after doing query rewrite for an updatable view
129 Fix planner's handling of <literal>LATERAL</> references (Tom
134 This fixes some corner cases that led to <quote>failed to build any
135 N-way joins</> or <quote>could not devise a query plan</> planner
142 Add more defenses against bad planner cost estimates for GIN index
143 scans when the index's internal statistics are very out-of-date
150 Make planner cope with hypothetical GIN indexes suggested by an index
151 advisor plug-in (Julien Rouhaud)
157 Speed up generation of unique table aliases in <command>EXPLAIN</> and
158 rule dumping, and ensure that generated aliases do not
159 exceed <literal>NAMEDATALEN</> (Tom Lane)
165 Fix dumping of whole-row Vars in <literal>ROW()</>
166 and <literal>VALUES()</> lists (Tom Lane)
172 Fix possible internal overflow in <type>numeric</> division
179 Fix enforcement of restrictions inside parentheses within regular
180 expression lookahead constraints (Tom Lane)
184 Lookahead constraints aren't allowed to contain backrefs, and
185 parentheses within them are always considered non-capturing, according
186 to the manual. However, the code failed to handle these cases properly
187 inside a parenthesized subexpression, and would give unexpected
194 Conversion of regular expressions to indexscan bounds could produce
195 incorrect bounds from regexps containing lookahead constraints
202 Fix regular-expression compiler to handle loops of constraint arcs
207 The code added for CVE-2007-4772 was both incomplete, in that it didn't
208 handle loops involving more than one state, and incorrect, in that it
209 could cause assertion failures (though there seem to be no bad
210 consequences of that in a non-assert build). Multi-state loops would
211 cause the compiler to run until the query was canceled or it reached
212 the too-many-states error condition.
218 Improve memory-usage accounting in regular-expression compiler
223 This causes the code to emit <quote>regular expression is too
224 complex</> errors in some cases that previously used unreasonable
225 amounts of time and memory.
231 Improve performance of regular-expression compiler (Tom Lane)
237 Make <literal>%h</> and <literal>%r</> escapes
238 in <varname>log_line_prefix</> work for messages emitted due
239 to <varname>log_connections</> (Tom Lane)
243 Previously, <literal>%h</>/<literal>%r</> started to work just after a
244 new session had emitted the <quote>connection received</> log message;
245 now they work for that message too.
251 On Windows, ensure the shared-memory mapping handle gets closed in
252 child processes that don't need it (Tom Lane, Amit Kapila)
256 This oversight resulted in failure to recover from crashes
257 whenever <varname>logging_collector</> is turned on.
263 Fix possible failure to detect socket EOF in non-blocking mode on
268 It's not entirely clear whether this problem can happen in pre-9.5
269 branches, but if it did, the symptom would be that a walsender process
270 would wait indefinitely rather than noticing a loss of connection.
276 Avoid leaking a token handle during SSPI authentication
283 In <application>psql</>, ensure that <application>libreadline</>'s idea
284 of the screen size is updated when the terminal window size changes
289 Previously, <application>libreadline</> did not notice if the window
290 was resized during query output, leading to strange behavior during
291 later input of multiline queries.
297 Fix <application>psql</>'s <literal>\det</> command to interpret its
298 pattern argument the same way as other <literal>\d</> commands with
299 potentially schema-qualified patterns do (Reece Hart)
305 Avoid possible crash in <application>psql</>'s <literal>\c</> command
306 when previous connection was via Unix socket and command specifies a
307 new hostname and same username (Tom Lane)
313 In <literal>pg_ctl start -w</>, test child process status directly
314 rather than relying on heuristics (Tom Lane, Michael Paquier)
318 Previously, <application>pg_ctl</> relied on an assumption that the new
319 postmaster would always create <filename>postmaster.pid</> within five
320 seconds. But that can fail on heavily-loaded systems,
321 causing <application>pg_ctl</> to report incorrectly that the
322 postmaster failed to start.
326 Except on Windows, this change also means that a <literal>pg_ctl start
327 -w</> done immediately after another such command will now reliably
328 fail, whereas previously it would report success if done within two
329 seconds of the first command.
335 In <literal>pg_ctl start -w</>, don't attempt to use a wildcard listen
336 address to connect to the postmaster (Kondo Yuta)
340 On Windows, <application>pg_ctl</> would fail to detect postmaster
341 startup if <varname>listen_addresses</> is set to <literal>0.0.0.0</>
342 or <literal>::</>, because it would try to use that value verbatim as
343 the address to connect to, which doesn't work. Instead assume
344 that <literal>127.0.0.1</> or <literal>::1</>, respectively, is the
351 In <application>pg_ctl</> on Windows, check service status to decide
352 where to send output, rather than checking if standard output is a
353 terminal (Michael Paquier)
359 In <application>pg_dump</> and <application>pg_basebackup</>, adopt
360 the GNU convention for handling tar-archive members exceeding 8GB
365 The POSIX standard for <literal>tar</> file format does not allow
366 archive member files to exceed 8GB, but most modern implementations
367 of <application>tar</> support an extension that fixes that. Adopt
368 this extension so that <application>pg_dump</> with <option>-Ft</> no
369 longer fails on tables with more than 8GB of data, and so
370 that <application>pg_basebackup</> can handle files larger than 8GB.
371 In addition, fix some portability issues that could cause failures for
372 members between 4GB and 8GB on some platforms. Potentially these
373 problems could cause unrecoverable data loss due to unreadable backup
380 Fix assorted corner-case bugs in <application>pg_dump</>'s processing
381 of extension member objects (Tom Lane)
387 Make <application>pg_dump</> mark a view's triggers as needing to be
388 processed after its rule, to prevent possible failure during
389 parallel <application>pg_restore</> (Tom Lane)
395 Ensure that relation option values are properly quoted
396 in <application>pg_dump</> (Kouhei Sutou, Tom Lane)
400 A reloption value that isn't a simple identifier or number could lead
401 to dump/reload failures due to syntax errors in CREATE statements
402 issued by <application>pg_dump</>. This is not an issue with any
403 reloption currently supported by core <productname>PostgreSQL</>, but
404 extensions could allow reloptions that cause the problem.
410 Avoid repeated password prompts during parallel <application>pg_dump</>
417 Fix <application>pg_upgrade</>'s file-copying code to handle errors
418 properly on Windows (Bruce Momjian)
424 Install guards in <application>pgbench</> against corner-case overflow
425 conditions during evaluation of script-specified division or modulo
426 operators (Fabien Coelho, Michael Paquier)
432 Fix failure to localize messages emitted
433 by <application>pg_receivexlog</> and <application>pg_recvlogical</>
440 Avoid dump/reload problems when using both <application>plpython2</>
441 and <application>plpython3</> (Tom Lane)
445 In principle, both versions of <application>PL/Python</> can be used in
446 the same database, though not in the same session (because the two
447 versions of <application>libpython</> cannot safely be used concurrently).
448 However, <application>pg_restore</> and <application>pg_upgrade</> both
449 do things that can fall foul of the same-session restriction. Work
450 around that by changing the timing of the check.
456 Fix <application>PL/Python</> regression tests to pass with Python 3.5
463 Fix premature clearing of <application>libpq</>'s input buffer when
464 socket EOF is seen (Tom Lane)
468 This mistake caused <application>libpq</> to sometimes not report the
469 backend's final error message before reporting <quote>server closed the
470 connection unexpectedly</>.
476 Prevent certain <application>PL/Java</> parameters from being set by
477 non-superusers (Noah Misch)
481 This change mitigates a <application>PL/Java</> security bug
482 (CVE-2016-0766), which was fixed in <application>PL/Java</> by marking
483 these parameters as superuser-only. To fix the security hazard for
484 sites that update <productname>PostgreSQL</> more frequently
485 than <application>PL/Java</>, make the core code aware of them also.
491 Improve <application>libpq</>'s handling of out-of-memory situations
492 (Michael Paquier, Amit Kapila, Heikki Linnakangas)
498 Fix order of arguments
499 in <application>ecpg</>-generated <literal>typedef</> statements
506 Use <literal>%g</> not <literal>%f</> format
507 in <application>ecpg</>'s <function>PGTYPESnumeric_from_double()</>
514 Fix <application>ecpg</>-supplied header files to not contain comments
515 continued from a preprocessor directive line onto the next line
520 Such a comment is rejected by <application>ecpg</>. It's not yet clear
521 whether <application>ecpg</> itself should be changed.
527 Fix <function>hstore_to_json_loose()</>'s test for whether
528 an <type>hstore</> value can be converted to a JSON number (Tom Lane)
532 Previously this function could be fooled by non-alphanumeric trailing
533 characters, leading to emitting syntactically-invalid JSON.
539 Ensure that <filename>contrib/pgcrypto</>'s <function>crypt()</>
540 function can be interrupted by query cancel (Andreas Karlsson)
546 Accept <application>flex</> versions later than 2.5.x
547 (Tom Lane, Michael Paquier)
551 Now that flex 2.6.0 has been released, the version checks in our build
552 scripts needed to be adjusted.
558 Improve reproducibility of build output by ensuring filenames are given
559 to the linker in a fixed order (Christoph Berg)
563 This avoids possible bitwise differences in the produced executable
564 files from one build to the next.
570 Install our <filename>missing</> script where PGXS builds can find it
575 This allows sane behavior in a PGXS build done on a machine where build
576 tools such as <application>bison</> are missing.
582 Ensure that <filename>dynloader.h</> is included in the installed
583 header files in MSVC builds (Bruce Momjian, Michael Paquier)
589 Add variant regression test expected-output file to match behavior of
590 current <application>libxml2</> (Tom Lane)
594 The fix for <application>libxml2</>'s CVE-2015-7499 causes it not to
595 output error context reports in some cases where it used to do so.
596 This seems to be a bug, but we'll probably have to live with it for
597 some time, so work around it.
603 Update time zone data files to <application>tzdata</> release 2016a for
604 DST law changes in Cayman Islands, Metlakatla, and Trans-Baikal
605 Territory (Zabaykalsky Krai), plus historical corrections for Pakistan.

615 <title>Release 9.3.10</title>
618 <title>Release Date</title>
619 <simpara>2015-10-08</simpara>
623 This release contains a variety of fixes from 9.3.9.
624 For information about new features in the 9.3 major release, see
625 <xref linkend="release-9-3">.
629 <title>Migration to Version 9.3.10</title>
632 A dump/restore is not required for those running 9.3.X.
636 However, if you are upgrading from a version earlier than 9.3.9,
637 see <xref linkend="release-9-3-9">.
643 <title>Changes</title>
649 Guard against stack overflows in <type>json</> parsing
654 If an application constructs PostgreSQL <type>json</>
655 or <type>jsonb</> values from arbitrary user input, the application's
656 users can reliably crash the PostgreSQL server, causing momentary
657 denial of service. (CVE-2015-5289)
663 Fix <filename>contrib/pgcrypto</> to detect and report
664 too-short <function>crypt()</> salts (Josh Kupershmidt)
668 Certain invalid salt arguments crashed the server or disclosed a few
669 bytes of server memory. We have not ruled out the viability of
670 attacks that arrange for presence of confidential information in the
671 disclosed bytes, but they seem unlikely. (CVE-2015-5288)
677 Fix subtransaction cleanup after a portal (cursor) belonging to an
678 outer subtransaction fails (Tom Lane, Michael Paquier)
682 A function executed in an outer-subtransaction cursor could cause an
683 assertion failure or crash by referencing a relation created within an
684 inner subtransaction.
690 Ensure all relations referred to by an updatable view are properly
691 locked during an update statement (Dean Rasheed)
697 Fix insertion of relations into the relation cache <quote>init file</>
702 An oversight in a patch in the most recent minor releases
703 caused <structname>pg_trigger_tgrelid_tgname_index</> to be omitted
704 from the init file. Subsequent sessions detected this, then deemed the
705 init file to be broken and silently ignored it, resulting in a
706 significant degradation in session startup time. In addition to fixing
707 the bug, install some guards so that any similar future mistake will be
714 Avoid O(N^2) behavior when inserting many tuples into a SPI query
721 Improve <command>LISTEN</> startup time when there are many unread
722 notifications (Matt Newell)
728 Fix performance problem when a session alters large numbers of foreign
729 key constraints (Jan Wieck, Tom Lane)
733 This was seen primarily when restoring <application>pg_dump</> output
734 for databases with many thousands of tables.
740 Disable SSL renegotiation by default (Michael Paquier, Andres Freund)
744 While use of SSL renegotiation is a good idea in theory, we have seen
745 too many bugs in practice, both in the underlying OpenSSL library and
746 in our usage of it. Renegotiation will be removed entirely in 9.5 and
747 later. In the older branches, just change the default value
748 of <varname>ssl_renegotiation_limit</> to zero (disabled).
754 Lower the minimum values of the <literal>*_freeze_max_age</> parameters
759 This is mainly to make tests of related behavior less time-consuming,
760 but it may also be of value for installations with limited disk space.
766 Limit the maximum value of <varname>wal_buffers</> to 2GB to avoid
767 server crashes (Josh Berkus)
773 Avoid logging complaints when a parameter that can only be set at
774 server start appears multiple times in <filename>postgresql.conf</>,
775 and fix counting of line numbers after an <literal>include_dir</>
782 Fix rare internal overflow in multiplication of <type>numeric</> values
789 Guard against hard-to-reach stack overflows involving record types,
790 range types, <type>json</>, <type>jsonb</>, <type>tsquery</>,
791 <type>ltxtquery</> and <type>query_int</> (Noah Misch)
797 Fix handling of <literal>DOW</> and <literal>DOY</> in datetime input
802 These tokens aren't meant to be used in datetime values, but previously
803 they resulted in opaque internal error messages rather
804 than <quote>invalid input syntax</>.
810 Add more query-cancel checks to regular expression matching (Tom Lane)
816 Add recursion depth protections to regular expression, <literal>SIMILAR
817 TO</>, and <literal>LIKE</> matching (Tom Lane)
821 Suitable search patterns and a low stack depth limit could lead to
822 stack-overrun crashes.
828 Fix potential infinite loop in regular expression execution (Tom Lane)
832 A search pattern that can apparently match a zero-length string, but
833 actually doesn't match because of a back reference, could lead to an
840 In regular expression execution, correctly record match data for
841 capturing parentheses within a quantifier even when the match is
842 zero-length (Tom Lane)
848 Fix low-memory failures in regular expression compilation
849 (Andreas Seltenreich)
855 Fix low-probability memory leak during regular expression execution
862 Fix rare low-memory failure in lock cleanup during transaction abort
869 Fix <quote>unexpected out-of-memory situation during sort</> errors
870 when using tuplestores with small <varname>work_mem</> settings (Tom
877 Fix very-low-probability stack overrun in <function>qsort</> (Tom Lane)
883 Fix <quote>invalid memory alloc request size</> failure in hash joins
884 with large <varname>work_mem</> settings (Tomas Vondra, Tom Lane)
890 Fix assorted planner bugs (Tom Lane)
894 These mistakes could lead to incorrect query plans that would give wrong
895 answers, or to assertion failures in assert-enabled builds, or to odd
896 planner errors such as <quote>could not devise a query plan for the
897 given query</>, <quote>could not find pathkey item to
898 sort</>, <quote>plan should not reference subplan's variable</>,
899 or <quote>failed to assign all NestLoopParams to plan nodes</>.
900 Thanks are due to Andreas Seltenreich and Piotr Stefaniak for fuzz
901 testing that exposed these problems.
907 Improve planner's performance for <command>UPDATE</>/<command>DELETE</>
908 on large inheritance sets (Tom Lane, Dean Rasheed)
914 Ensure standby promotion trigger files are removed at postmaster
915 startup (Michael Paquier, Fujii Masao)
919 This prevents unwanted promotion from occurring if these files appear
920 in a database backup that is used to initialize a new standby server.
926 During postmaster shutdown, ensure that per-socket lock files are
927 removed and listen sockets are closed before we remove
928 the <filename>postmaster.pid</> file (Tom Lane)
932 This avoids race-condition failures if an external script attempts to
933 start a new postmaster as soon as <literal>pg_ctl stop</> returns.
939 Fix postmaster's handling of a startup-process crash during crash
944 If, during a crash recovery cycle, the startup process crashes without
945 having restored database consistency, we'd try to launch a new startup
946 process, which typically would just crash again, leading to an infinite
953 Make emergency autovacuuming for multixact wraparound more robust
960 Do not print a <literal>WARNING</> when an autovacuum worker is already
961 gone when we attempt to signal it, and reduce log verbosity for such
968 Prevent autovacuum launcher from sleeping unduly long if the server
969 clock is moved backwards a large amount (Álvaro Herrera)
975 Ensure that cleanup of a GIN index's pending-insertions list is
976 interruptable by cancel requests (Jeff Janes)
982 Allow all-zeroes pages in GIN indexes to be reused (Heikki Linnakangas)
986 Such a page might be left behind after a crash.
992 Fix handling of all-zeroes pages in SP-GiST indexes (Heikki
997 <command>VACUUM</> attempted to recycle such pages, but did so in a
998 way that wasn't crash-safe.
1004 Fix off-by-one error that led to otherwise-harmless warnings
1005 about <quote>apparent wraparound</> in subtrans/multixact truncation
1012 Fix misreporting of <command>CONTINUE</> and <command>MOVE</> statement
1013 types in <application>PL/pgSQL</>'s error context messages
1014 (Pavel Stehule, Tom Lane)
1020 Fix <application>PL/Perl</> to handle non-<acronym>ASCII</> error
1021 message texts correctly (Alex Hunsaker)
1027 Fix <application>PL/Python</> crash when returning the string
1028 representation of a <type>record</> result (Tom Lane)
1034 Fix some places in <application>PL/Tcl</> that neglected to check for
1035 failure of <function>malloc()</> calls (Michael Paquier, Álvaro
1042 In <filename>contrib/isn</>, fix output of ISBN-13 numbers that begin
1043 with 979 (Fabien Coelho)
1047 EANs beginning with 979 (but not 9790) are considered ISBNs, but they
1048 must be printed in the new 13-digit format, not the 10-digit format.
1054 Improve <filename>contrib/postgres_fdw</>'s handling of
1055 collation-related decisions (Tom Lane)
1059 The main user-visible effect is expected to be that comparisons
1060 involving <type>varchar</> columns will be sent to the remote server
1061 for execution in more cases than before.
1067 Improve <application>libpq</>'s handling of out-of-memory conditions
1068 (Michael Paquier, Heikki Linnakangas)
1074 Fix memory leaks and missing out-of-memory checks
1075 in <application>ecpg</> (Michael Paquier)
1081 Fix <application>psql</>'s code for locale-aware formatting of numeric
1086 The formatting code invoked by <literal>\pset numericlocale on</>
1087 did the wrong thing for some uncommon cases such as numbers with an
1088 exponent but no decimal point. It could also mangle already-localized
1089 output from the <type>money</> data type.
1095 Prevent crash in <application>psql</>'s <command>\c</> command when
1096 there is no current connection (Noah Misch)
1102 Make <application>pg_dump</> handle inherited <literal>NOT VALID</>
1103 check constraints correctly (Tom Lane)
1109 Fix selection of default <application>zlib</> compression level
1110 in <application>pg_dump</>'s directory output format (Andrew Dunstan)
1116 Ensure that temporary files created during a <application>pg_dump</>
1117 run with <acronym>tar</>-format output are not world-readable (Michael
1124 Fix <application>pg_dump</> and <application>pg_upgrade</> to support
1125 cases where the <literal>postgres</> or <literal>template1</> database
1126 is in a non-default tablespace (Marti Raudsepp, Bruce Momjian)
1132 Fix <application>pg_dump</> to handle object privileges sanely when
1133 dumping from a server too old to have a particular privilege type
1138 When dumping data types from pre-9.2 servers, and when dumping
1139 functions or procedural languages from pre-7.3
1140 servers, <application>pg_dump</> would
1141 produce <command>GRANT</>/<command>REVOKE</> commands that revoked the
1142 owner's grantable privileges and instead granted all privileges
1143 to <literal>PUBLIC</>. Since the privileges involved are
1144 just <literal>USAGE</> and <literal>EXECUTE</>, this isn't a security
1145 problem, but it's certainly a surprising representation of the older
1146 systems' behavior. Fix it to leave the default privilege state alone
1153 Fix <application>pg_dump</> to dump shell types (Tom Lane)
1157 Shell types (that is, not-yet-fully-defined types) aren't useful for
1158 much, but nonetheless <application>pg_dump</> should dump them.
1164 Fix assorted minor memory leaks in <application>pg_dump</> and other
1165 client-side programs (Michael Paquier)
1171 Fix spinlock assembly code for PPC hardware to be compatible
1172 with <acronym>AIX</>'s native assembler (Tom Lane)
1176 Building with <application>gcc</> didn't work if <application>gcc</>
1177 had been configured to use the native assembler, which is becoming more
1184 On <acronym>AIX</>, test the <literal>-qlonglong</> compiler option
1185 rather than just assuming it's safe to use (Noah Misch)
1191 On <acronym>AIX</>, use <literal>-Wl,-brtllib</> link option to allow
1192 symbols to be resolved at runtime (Noah Misch)
1196 Perl relies on this ability in 5.8.0 and later.
1202 Avoid use of inline functions when compiling with
1203 32-bit <application>xlc</>, due to compiler bugs (Noah Misch)
1209 Use <filename>librt</> for <function>sched_yield()</> when necessary,
1210 which it is on some Solaris versions (Oskari Saarenmaa)
1216 Fix Windows <filename>install.bat</> script to handle target directory
1217 names that contain spaces (Heikki Linnakangas)
1223 Make the numeric form of the <productname>PostgreSQL</> version number
1224 (e.g., <literal>90405</>) readily available to extension Makefiles,
1225 as a variable named <varname>VERSION_NUM</> (Michael Paquier)
1231 Update time zone data files to <application>tzdata</> release 2015g for
1232 DST law changes in Cayman Islands, Fiji, Moldova, Morocco, Norfolk
1233 Island, North Korea, Turkey, and Uruguay. There is a new zone name
1234 <literal>America/Fort_Nelson</> for the Canadian Northern Rockies.

1258 <title>Migration to Version 9.3.9</title>
1261 A dump/restore is not required for those running 9.3.X.
1265 However, if you are upgrading an installation that was previously
1266 upgraded using a <application>pg_upgrade</> version between 9.3.0 and
1267 9.3.4 inclusive, see the first changelog entry below.
1271 Also, if you are upgrading from a version earlier than 9.3.7,
1272 see <xref linkend="release-9-3-7">.
1278 <title>Changes</title>
1284 Fix possible failure to recover from an inconsistent database state
1289 Recent <productname>PostgreSQL</> releases introduced mechanisms to
1290 protect against multixact wraparound, but some of that code did not
1291 account for the possibility that it would need to run during crash
1292 recovery, when the database may not be in a consistent state. This
1293 could result in failure to restart after a crash, or failure to start
1294 up a secondary server. The lingering effects of a previously-fixed
1295 bug in <application>pg_upgrade</> could also cause such a failure, in
1296 installations that had used <application>pg_upgrade</> versions
1297 between 9.3.0 and 9.3.4.
1301 The <application>pg_upgrade</> bug in question was that it would
1302 set <literal>oldestMultiXid</> to 1 in <filename>pg_control</> even
1303 if the true value should be higher. With the fixes introduced in
1304 this release, such a situation will result in immediate emergency
1305 autovacuuming until a correct <literal>oldestMultiXid</> value can be
1306 determined. If that would pose a hardship, users can avoid it by
1307 doing manual vacuuming <emphasis>before</> upgrading to this release.
1313 Check whether <application>pg_controldata</> reports <quote>Latest
1314 checkpoint's oldestMultiXid</> to be 1. If not, there's nothing
1320 Look in <filename>PGDATA/pg_multixact/offsets</> to see if there's a
1321 file named <filename>0000</>. If there is, there's nothing to do.
1326 Otherwise, for each table that has
1327 <structname>pg_class</>.<structfield>relminmxid</> equal to 1,
1328 <command>VACUUM</> that table with
1329 both <xref linkend="guc-vacuum-multixact-freeze-min-age">
1330 and <xref linkend="guc-vacuum-multixact-freeze-table-age"> set to
1331 zero. (You can use the vacuum cost delay parameters described
1332 in <xref linkend="runtime-config-resource-vacuum-cost"> to reduce
1333 the performance consequences for concurrent sessions.) You must
1334 use <productname>PostgreSQL</> 9.3.5 or later to perform this step.
1343 Fix rare failure to invalidate relation cache init file (Tom Lane)
1347 With just the wrong timing of concurrent activity, a <command>VACUUM
1348 FULL</> on a system catalog might fail to update the <quote>init file</>
1349 that's used to avoid cache-loading work for new sessions. This would
1350 result in later sessions being unable to access that catalog at all.
1351 This is a very ancient bug, but it's so hard to trigger that no
1352 reproducible case had been seen until recently.
1358 Avoid deadlock between incoming sessions and <literal>CREATE/DROP
1359 DATABASE</> (Tom Lane)
1363 A new session starting in a database that is the target of
1364 a <command>DROP DATABASE</> command, or is the template for
1365 a <command>CREATE DATABASE</> command, could cause the command to wait
1366 for five seconds and then fail, even if the new session would have
1373 Improve planner's cost estimates for semi-joins and anti-joins with
1374 inner indexscans (Tom Lane, Tomas Vondra)
1378 This type of plan is quite cheap when all the join clauses are used
1379 as index scan conditions, even if the inner scan would nominally
1380 fetch many rows, because the executor will stop after obtaining one
1381 row. The planner only partially accounted for that effect, and would
1382 therefore overestimate the cost, leading it to possibly choose some
1383 other much less efficient plan type.

1421 <title>Changes</title>
1427 Avoid failures while <function>fsync</>'ing data directory during
1428 crash restart (Abhijit Menon-Sen, Tom Lane)
1432 In the previous minor releases we added a patch to <function>fsync</>
1433 everything in the data directory after a crash. Unfortunately its
1434 response to any error condition was to fail, thereby preventing the
1435 server from starting up, even when the problem was quite harmless.
1436 An example is that an unwritable file in the data directory would
1437 prevent restart on some platforms; but it is common to make SSL
1438 certificate files unwritable by the server. Revise this behavior so
1439 that permissions failures are ignored altogether, and other types of
1440 failures are logged but do not prevent continuing.
1444 Also apply the same rules in <literal>initdb --sync-only</>.
1445 This case is less critical but it should act similarly.
1451 Fix <function>pg_get_functiondef()</> to show
1452 functions' <literal>LEAKPROOF</> property, if set (Jeevan Chalke)
1458 Remove <application>configure</>'s check prohibiting linking to a
1459 threaded <application>libpython</>
1460 on <systemitem class="osname">OpenBSD</> (Tom Lane)

1480 Allow <application>libpq</> to use TLS protocol versions beyond v1
1485 For a long time, <application>libpq</> was coded so that the only SSL
1486 protocol it would allow was TLS v1. Now that newer TLS versions are
1487 becoming popular, allow it to negotiate the highest commonly-supported
1488 TLS version with the server. (<productname>PostgreSQL</> servers were
1489 already capable of such negotiation, so no change is needed on the
1490 server side.) This is a back-patch of a change already released in

1535 <title>Changes</title>
1541 Avoid possible crash when client disconnects just before the
1542 authentication timeout expires (Benkocs Norbert Attila)
1546 If the timeout interrupt fired partway through the session shutdown
1547 sequence, SSL-related state would be freed twice, typically causing a
1548 crash and hence denial of service to other sessions. Experimentation
1549 shows that an unauthenticated remote attacker could trigger the bug
1550 somewhat consistently, hence treat as security issue.
1557 Improve detection of system-call failures (Noah Misch)
1561 Our replacement implementation of <function>snprintf()</> failed to
1562 check for errors reported by the underlying system library calls;
1563 the main case that might be missed is out-of-memory situations.
1564 In the worst case this might lead to information exposure, due to our
1565 code assuming that a buffer had been overwritten when it hadn't been.
1566 Also, there were a few places in which security-relevant calls of other
1567 system library functions did not check for failure.
1571 It remains possible that some calls of the <function>*printf()</>
1572 family of functions are vulnerable to information disclosure if an
1573 out-of-memory error occurs at just the wrong time. We judge the risk
1574 to not be large, but will continue analysis in this area.
1581 In <filename>contrib/pgcrypto</>, uniformly report decryption failures
1582 as <quote>Wrong key or corrupt data</> (Noah Misch)
1586 Previously, some cases of decryption with an incorrect key could report
1587 other error message texts. It has been shown that such variance in
1588 error reports can aid attackers in recovering keys from other systems.
1589 While it's unknown whether <filename>pgcrypto</>'s specific behaviors
1590 are likewise exploitable, it seems better to avoid the risk by using a
1591 one-size-fits-all message.
1598 Protect against wraparound of multixact member IDs
1599 (Álvaro Herrera, Robert Haas, Thomas Munro)
1603 Under certain usage patterns, the existing defenses against this might
1604 be insufficient, allowing <filename>pg_multixact/members</> files to be
1605 removed too early, resulting in data loss.
1606 The fix for this includes modifying the server to fail transactions
1607 that would result in overwriting old multixact member ID data, and
1608 improving autovacuum to ensure it will act proactively to prevent
1609 multixact member ID wraparound, as it does for transaction ID
1616 Fix incorrect declaration of <filename>contrib/citext</>'s
1617 <function>regexp_matches()</> functions (Tom Lane)
1621 These functions should return <type>setof text[]</>, like the core
1622 functions they are wrappers for; but they were incorrectly declared as
1623 returning just <type>text[]</>. This mistake had two results: first,
1624 if there was no match you got a scalar null result, whereas what you
1625 should get is an empty set (zero rows). Second, the <literal>g</> flag
1626 was effectively ignored, since you would get only one result array even
1627 if there were multiple matches.
1631 While the latter behavior is clearly a bug, there might be applications
1632 depending on the former behavior; therefore the function declarations
1633 will not be changed by default until <productname>PostgreSQL</> 9.5.
1634 In pre-9.5 branches, the old behavior exists in version 1.0 of
1635 the <literal>citext</> extension, while we have provided corrected
1636 declarations in version 1.1 (which is <emphasis>not</> installed by
1637 default). To adopt the fix in pre-9.5 branches, execute
1638 <literal>ALTER EXTENSION citext UPDATE TO '1.1'</> in each database in
1639 which <literal>citext</> is installed. (You can also <quote>update</>
1640 back to 1.0 if you need to undo that.) Be aware that either update
1641 direction will require dropping and recreating any views or rules that
1642 use <filename>citext</>'s <function>regexp_matches()</> functions.
1648 Fix incorrect checking of deferred exclusion constraints after a HOT
1653 If a new row that potentially violates a deferred exclusion constraint
1654 is HOT-updated (that is, no indexed columns change and the row can be
1655 stored back onto the same table page) later in the same transaction,
1656 the exclusion constraint would be reported as violated when the check
1657 finally occurred, even if the row(s) the new row originally conflicted
1658 with had been deleted.
1664 Fix planning of star-schema-style queries (Tom Lane)
1668 Sometimes, efficient scanning of a large table requires that index
1669 parameters be provided from more than one other table (commonly,
1670 dimension tables whose keys are needed to index a large fact table).
1671 The planner should be able to find such plans, but an overly
1672 restrictive search heuristic prevented it.
1678 Prevent improper reordering of antijoins (NOT EXISTS joins) versus
1679 other outer joins (Tom Lane)
1683 This oversight in the planner has been observed to cause <quote>could
1684 not find RelOptInfo for given relids</> errors, but it seems possible
1685 that sometimes an incorrect query plan might get past that consistency
1686 check and result in silently-wrong query output.
1692 Fix incorrect matching of subexpressions in outer-join plan nodes
1697 Previously, if textually identical non-strict subexpressions were used
1698 both above and below an outer join, the planner might try to re-use
1699 the value computed below the join, which would be incorrect because the
1700 executor would force the value to NULL in case of an unmatched outer row.
1706 Fix GEQO planner to cope with failure of its join order heuristic
1711 This oversight has been seen to lead to <quote>failed to join all
1712 relations together</> errors in queries involving <literal>LATERAL</>,
1713 and that might happen in other cases as well.
1719 Fix possible deadlock at startup
1720 when <literal>max_prepared_transactions</> is too small
1721 (Heikki Linnakangas)
1727 Don't archive useless preallocated WAL files after a timeline switch
1728 (Heikki Linnakangas)
1734 Recursively <function>fsync()</> the data directory after a crash
1735 (Abhijit Menon-Sen, Robert Haas)
1739 This ensures consistency if another crash occurs shortly later. (The
1740 second crash would have to be a system-level crash, not just a database
1741 crash, for there to be a problem.)
1747 Fix autovacuum launcher's possible failure to shut down, if an error
1748 occurs after it receives SIGTERM (Álvaro Herrera)
1754 Cope with unexpected signals in <function>LockBufferForCleanup()</>
1759 This oversight could result in spurious errors about <quote>multiple
1760 backends attempting to wait for pincount 1</>.
1766 Fix crash when doing <literal>COPY IN</> to a table with check
1767 constraints that contain whole-row references (Tom Lane)
1771 The known failure case only crashes in 9.4 and up, but there is very
1772 similar code in 9.3 and 9.2, so back-patch those branches as well.
1778 Avoid waiting for WAL flush or synchronous replication during commit of
1779 a transaction that was read-only so far as the user is concerned
1784 Previously, a delay could occur at commit in transactions that had
1785 written WAL due to HOT page pruning, leading to undesirable effects
1786 such as sessions getting stuck at startup if all synchronous replicas
1787 are down. Sessions have also been observed to get stuck in catchup
1788 interrupt processing when using synchronous replication; this will fix
1789 that problem as well.
1795 Fix crash when manipulating hash indexes on temporary tables
1796 (Heikki Linnakangas)
1802 Fix possible failure during hash index bucket split, if other processes
1803 are modifying the index concurrently (Tom Lane)
1809 Check for interrupts while analyzing index expressions (Jeff Janes)
1813 <command>ANALYZE</> executes index expressions many times; if there are
1814 slow functions in such an expression, it's desirable to be able to
1815 cancel the <command>ANALYZE</> before that loop finishes.
1821 Ensure <structfield>tableoid</> of a foreign table is reported
1822 correctly when a <literal>READ COMMITTED</> recheck occurs after
1823 locking rows in <command>SELECT FOR UPDATE</>, <command>UPDATE</>,
1824 or <command>DELETE</> (Etsuro Fujita)
1830 Add the name of the target server to object description strings for
1831 foreign-server user mappings (Álvaro Herrera)
1837 Include the schema name in object identity strings for conversions
1838 (Álvaro Herrera)
1844 Recommend setting <literal>include_realm</> to 1 when using
1845 Kerberos/GSSAPI/SSPI authentication (Stephen Frost)
1849 Without this, identically-named users from different realms cannot be
1850 distinguished. For the moment this is only a documentation change, but
1851 it will become the default setting in <productname>PostgreSQL</> 9.5.
1857 Remove code for matching IPv4 <filename>pg_hba.conf</> entries to
1858 IPv4-in-IPv6 addresses (Tom Lane)
1862 This hack was added in 2003 in response to a report that some Linux
1863 kernels of the time would report IPv4 connections as having
1864 IPv4-in-IPv6 addresses. However, the logic was accidentally broken in
1865 9.0. The lack of any field complaints since then shows that it's not
1866 needed anymore. Now we have reports that the broken code causes
1867 crashes on some systems, so let's just remove it rather than fix it.
1868 (Had we chosen to fix it, that would make for a subtle and potentially
1869 security-sensitive change in the effective meaning of
1870 IPv4 <filename>pg_hba.conf</> entries, which does not seem like a good
1871 thing to do in minor releases.)
1877 Report WAL flush, not insert, position in <literal>IDENTIFY_SYSTEM</>
1878 replication command (Heikki Linnakangas)
1882 This avoids a possible startup failure
1883 in <application>pg_receivexlog</>.
1889 While shutting down service on Windows, periodically send status
1890 updates to the Service Control Manager to prevent it from killing the
1891 service too soon; and ensure that <application>pg_ctl</> will wait for
1892 shutdown (Krystian Bigaj)
1898 Reduce risk of network deadlock when using <application>libpq</>'s
1899 non-blocking mode (Heikki Linnakangas)
1903 When sending large volumes of data, it's important to drain the input
1904 buffer every so often, in case the server has sent enough response data
1905 to cause it to block on output. (A typical scenario is that the server
1906 is sending a stream of NOTICE messages during <literal>COPY FROM
1907 STDIN</>.) This worked properly in the normal blocking mode, but not
1908 so much in non-blocking mode. We've modified <application>libpq</>
1909 to opportunistically drain input when it can, but a full defense
1910 against this problem requires application cooperation: the application
1911 should watch for socket read-ready as well as write-ready conditions,
1912 and be sure to call <function>PQconsumeInput()</> upon read-ready.
1918 In <application>libpq</>, fix misparsing of empty values in URI
1919 connection strings (Thomas Fanghaenel)
1925 Fix array handling in <application>ecpg</> (Michael Meskes)
1931 Fix <application>psql</> to sanely handle URIs and conninfo strings as
1932 the first parameter to <command>\connect</>
1933 (David Fetter, Andrew Dunstan, Álvaro Herrera)
1937 This syntax has been accepted (but undocumented) for a long time, but
1938 previously some parameters might be taken from the old connection
1939 instead of the given string, which was agreed to be undesirable.
1945 Suppress incorrect complaints from <application>psql</> on some
1946 platforms that it failed to write <filename>~/.psql_history</> at exit
1951 This misbehavior was caused by a workaround for a bug in very old
1952 (pre-2006) versions of <application>libedit</>. We fixed it by
1953 removing the workaround, which will cause a similar failure to appear
1954 for anyone still using such versions of <application>libedit</>.
1955 Recommendation: upgrade that library, or use <application>libreadline</>.
1961 Fix <application>pg_dump</>'s rule for deciding which casts are
1962 system-provided casts that should not be dumped (Tom Lane)
1968 In <application>pg_dump</>, fix failure to honor <literal>-Z</>
1969 compression level option together with <literal>-Fd</>
1976 Make <application>pg_dump</> consider foreign key relationships
1977 between extension configuration tables while choosing dump order
1978 (Gilles Darold, Michael Paquier, Stephen Frost)
1982 This oversight could result in producing dumps that fail to reload
1983 because foreign key constraints are transiently violated.
1989 Avoid possible <application>pg_dump</> failure when concurrent sessions
1990 are creating and dropping temporary functions (Tom Lane)
1996 Fix dumping of views that are just <literal>VALUES(...)</> but have
1997 column aliases (Tom Lane)
2003 In <application>pg_upgrade</>, force timeline 1 in the new cluster
2008 This change prevents upgrade failures caused by bogus complaints about
2009 missing WAL history files.
2015 In <application>pg_upgrade</>, check for improperly non-connectable
2016 databases before proceeding
2023 In <application>pg_upgrade</>, quote directory paths
2024 properly in the generated <literal>delete_old_cluster</> script
2031 In <application>pg_upgrade</>, preserve database-level freezing info
2037 This oversight could cause missing-clog-file errors for tables within
2038 the <literal>postgres</> and <literal>template1</> databases.
2044 Run <application>pg_upgrade</> and <application>pg_resetxlog</> with
2045 restricted privileges on Windows, so that they don't fail when run by
2046 an administrator (Muhammad Asif Naeem)
2052 Improve handling of <function>readdir()</> failures when scanning
2053 directories in <application>initdb</> and <application>pg_basebackup</>
2060 Fix slow sorting algorithm in <filename>contrib/intarray</> (Tom Lane)
2066 Fix compile failure on Sparc V8 machines (Rob Rowan)
2072 Silence some build warnings on OS X (Tom Lane)
2078 Update time zone data files to <application>tzdata</> release 2015d
2079 for DST law changes in Egypt, Mongolia, and Palestine, plus historical
2080 changes in Canada and Chile. Also adopt revised zone abbreviations for
2081 the America/Adak zone (HST/HDT not HAST/HADT).

2156 When <function>to_char()</> processes a numeric formatting template

2179 Fix buffer overrun in replacement <function>*printf()</> functions
2184 <productname>PostgreSQL</> includes a replacement implementation
2185 of <function>printf</> and related functions. This code will overrun
2186 a stack buffer when formatting a floating point number (conversion
2187 specifiers <literal>e</>, <literal>E</>, <literal>f</>, <literal>F</>,
2188 <literal>g</> or <literal>G</>) with requested precision greater than
2189 about 500. This will crash the server, and we have not ruled out the
2190 possibility of attacks that lead to privilege escalation.
2191 A database user can trigger such a buffer overrun through
2192 the <function>to_char()</> SQL function. While that is the only
2193 affected core <productname>PostgreSQL</> functionality, extension
2194 modules that use printf-family functions may be at risk as well.
2198 This issue primarily affects <productname>PostgreSQL</> on Windows.
2199 <productname>PostgreSQL</> uses the system implementation of these
2200 functions where adequate, which it is on other modern platforms.

2250 Fix possible loss of frontend/backend protocol synchronization after
2252 (Heikki Linnakangas)
2256 If any error occurred while the server was in the middle of reading a
2257 protocol message from the client, it could lose synchronization and
2258 incorrectly try to interpret part of the message's data as a new
2259 protocol message. An attacker able to submit crafted binary data
2260 within a command parameter might succeed in injecting his own SQL
2261 commands this way. Statement timeout and query cancellation are the
2262 most likely sources of errors triggering this scenario. Particularly
2263 vulnerable are applications that use a timeout and also submit
2264 arbitrary user-crafted data as binary query parameters. Disabling
2265 statement timeout will reduce, but not eliminate, the risk of
2266 exploit. Our thanks to Emil Lenngren for reporting this issue.

2667 never be less than the number of nonzero fractional digits; but
2668 apparently there's at least one broken client application that
2669 transmits binary <type>numeric</> values in which that's true.
2670 This leads to strange behavior since the extra digits are taken into
2671 account by arithmetic operations even though they aren't printed.
2672 The least risky fix seems to be to truncate away such <quote>hidden</>
2673 digits on receipt, so that the value is indeed what it prints as.

2931 The previous behavior resulted in basically ignoring these per-table

2933 will be vacuumed using those settings, independently of what is going
2934 on in other autovacuum workers. This may result in heavier total I/O

3267 Fix <application>psql</>'s <command>\s</> command to work nicely with
3268 libedit, and add pager support (Stepan Rutz, Tom Lane)
3272 When using libedit rather than readline, <command>\s</> printed the
3273 command history in a fairly unreadable encoded format, and on recent
3274 libedit versions might fail altogether. Fix that by printing the
3275 history ourselves rather than having the library do it. A pleasant
3276 side-effect is that the pager is used if appropriate.
3280 This patch also fixes a bug that caused newline encoding to be applied
3281 inconsistently when saving the command history with libedit.
3282 Multiline history entries written by older <application>psql</>
3283 versions will be read cleanly with this patch, but perhaps not
3284 vice versa, depending on the exact libedit versions involved.

3876 Support time zone abbreviations that change UTC offset from time to
3881 Previously, <productname>PostgreSQL</> assumed that the UTC offset
3882 associated with a time zone abbreviation (such as <literal>EST</>)
3883 never changes in the usage of any particular locale. However this
3884 assumption fails in the real world, so introduce the ability for a
3885 zone abbreviation to represent a UTC offset that sometimes changes.
3886 Update the zone abbreviation definition files to make use of this
3887 feature in timezone locales that have changed the UTC offset of their
3888 abbreviations since 1970 (according to the IANA timezone database).
3889 In such timezones, <productname>PostgreSQL</> will now associate the
3890 correct UTC offset with the abbreviation depending on the given date.

3943 Update time zone data files to <application>tzdata</> release 2015a.
3947 The IANA timezone database has adopted abbreviations of the form
3948 <literal>A<replaceable>x</>ST</literal>/<literal>A<replaceable>x</>DT</literal>
3949 for all Australian time zones, reflecting what they believe to be
3950 current majority practice Down Under. These names do not conflict
3951 with usage elsewhere (other than ACST for Acre Summer Time, which has
3952 been in disuse since 1994). Accordingly, adopt these names into
3953 our <quote>Default</> timezone abbreviation set.
3954 The <quote>Australia</> abbreviation set now contains only CST, EAST,
3955 EST, SAST, SAT, and WST, all of which are thought to be mostly
3956 historical usage. Note that SAST has also been changed to be South
3957 Africa Standard Time in the <quote>Default</> abbreviation set.
3961 Also, add zone abbreviations SRET (Asia/Srednekolymsk) and XJT
3962 (Asia/Urumqi), and use WSST/WSDT for western Samoa. Also, there were
3963 DST law changes in Chile, Mexico, the Turks & Caicos Islands
3964 (America/Grand_Turk), and Fiji. There is a new zone
3965 Pacific/Bougainville for portions of Papua New Guinea. Also, numerous
3966 corrections for historical (pre-1970) time zone data.

4025 In <application>pg_upgrade</>, remove <filename>pg_multixact</> files
4026 left behind by <application>initdb</> (Bruce Momjian)
4030 If you used a pre-9.3.5 version of <application>pg_upgrade</> to
4031 upgrade a database cluster to 9.3, it might have left behind a file
4032 <filename>$PGDATA/pg_multixact/offsets/0000</> that should not be
4033 there and will eventually cause problems in <command>VACUUM</>.
4034 <emphasis>However, in common cases this file is actually valid and
4035 must not be removed.</emphasis>
4036 To determine whether your installation has this problem, run this
4037 query as superuser, in any database of the cluster:
4039 WITH list(file) AS (SELECT * FROM pg_ls_dir('pg_multixact/offsets'))
4040 SELECT EXISTS (SELECT * FROM list WHERE file = '0000') AND
4041 NOT EXISTS (SELECT * FROM list WHERE file = '0001') AND
4042 NOT EXISTS (SELECT * FROM list WHERE file = 'FFFF') AND
4043 EXISTS (SELECT * FROM list WHERE file != '0000')
4044 AS file_0000_removal_required;
4046 If this query returns <literal>t</>, manually remove the file
4047 <filename>$PGDATA/pg_multixact/offsets/0000</>.
4048 Do nothing if the query returns <literal>f</>.

4560 Reduce indentation in rule/view dumps to improve readability and avoid
4561 excessive whitespace (Greg Stark, Tom Lane)
4565 This change reduces the amount of indentation applied to nested
4566 constructs, including some cases that the user probably doesn't think
4567 of as nested, such as UNION lists. Previously, deeply nested
4568 constructs were printed with an amount of whitespace growing as
4569 O(N^2), which created a performance problem and even risk of
4570 out-of-memory failures. Now the indentation is reduced modulo 40,
4571 which is initially odd to look at but seems to preserve readability
4572 better than simply limiting the indentation would do.
4573 Redundant parenthesization of UNION lists has been reduced as well.

4683 Secure Unix-domain sockets of temporary postmasters started during
4684 <literal>make check</> (Noah Misch)
4688 Any local user able to access the socket file could connect as the
4689 server's bootstrap superuser, then proceed to execute arbitrary code as
4690 the operating-system user running the test, as we previously noted in
4691 CVE-2014-0067. This change defends against that risk by placing the
4692 server's socket in a temporary, mode 0700 subdirectory
4693 of <filename>/tmp</>. The hazard remains however on platforms where
4694 Unix sockets are not supported, notably Windows, because then the
4695 temporary postmaster must accept local TCP connections.
4699 A useful side effect of this change is to simplify
4700 <literal>make check</> testing in builds that
4701 override <literal>DEFAULT_PGSOCKET_DIR</>. Popular non-default values
4702 like <filename>/var/run/postgresql</> are often not writable by the
4703 build user, requiring workarounds that will no longer be necessary.

4823 as <quote>lost synchronization with server</>). Under ordinary
4824 circumstances it's quite far-fetched that data could be continuously

4827 slowed by scheduler constraints.

5099 <title>Release Date</title>
5100 <simpara>2014-03-20</simpara>
5104 This release contains a variety of fixes from 9.3.3.
5105 For information about new features in the 9.3 major release, see

5110 <title>Migration to Version 9.3.4</title>
5113 A dump/restore is not required for those running 9.3.X.
5117 However, the error fixed in the first changelog entry below could have
5118 resulted in corrupt data on standby servers. It may be prudent to
5119 reinitialize standby servers from fresh base backups after installing

5143 Fix WAL replay of locking an already-updated tuple (Andres Freund,
5144 Álvaro Herrera)
5148 This error caused updated rows to not be found by index scans, resulting
5149 in inconsistent query results depending on whether an index scan was
5150 used. Subsequent processing could result in constraint violations,
5151 since the previously updated row would not be found by later index
5152 searches, thus possibly allowing conflicting rows to be inserted.
5153 Since this error is in WAL replay, it would only manifest during crash
5154 recovery or on standby servers. The improperly-replayed case most
5155 commonly arises when a table row that is referenced by a foreign-key
5156 constraint is updated concurrently with creation of a referencing row.

5172 Restore GIN metapages unconditionally to avoid torn-page risk
5173 (Heikki Linnakangas)
5177 Although this oversight could theoretically result in a corrupted
5178 index, it is unlikely to have caused any problems in practice, since

5310 This change fixes a significant performance problem that occurred
5311 when there were many not-yet-committed rows at the end of the index,
5312 which is a common situation for indexes on sequentially-assigned
5313 values such as timestamps or sequence-generated identifiers.

5346 This fix prevents a permanent leak of statistics file space.
5347 Users who have done many <command>DROP DATABASE</> commands since

5558 <title>Release 9.3.3</title>
5561 <title>Release Date</title>
5562 <simpara>2014-02-20</simpara>
5566 This release contains a variety of fixes from 9.3.2.
5567 For information about new features in the 9.3 major release, see
5568 <xref linkend="release-9-3">.
5572 <title>Migration to Version 9.3.3</title>
5575 A dump/restore is not required for those running 9.3.X.
5579 However, several of the issues corrected in this release could have
5580 resulted in corruption of foreign-key constraints; that is, there
5581 might now be referencing rows for which there is no matching row in
5582 the referenced table. It may be worthwhile to recheck such
5583 constraints after installing this update. The simplest way to do that
5584 is to drop and recreate each suspect constraint; however, that will
5585 require taking an exclusive lock on both tables, so it is unlikely to
5586 be acceptable in production databases. Alternatively, you can do a
5587 manual join query between the two tables to look for unmatched rows.
5591 Note also the requirement for replication standby servers to be
5592 upgraded before their master server is upgraded.
5596 Also, if you are upgrading from a version earlier than 9.3.2,
5597 see <xref linkend="release-9-3-2">.

5625 prevent the grantee from adding or removing members from the granted
5626 role, but this restriction was easily bypassed by doing <literal>SET
5627 ROLE</> first. The security impact is mostly that a role member can
5628 revoke the access of others, contrary to the wishes of his grantor.
5629 Unapproved role member additions are a lesser concern, since an
5630 uncooperative role member could provide most of his rights to others
5631 anyway by creating views or <literal>SECURITY DEFINER</> functions.

5648 Prevent privilege escalation via manual calls to PL validator
5649 functions (Andres Freund)
5653 The primary role of PL validator functions is to be called implicitly
5654 during <command>CREATE FUNCTION</>, but they are also normal SQL
5655 functions that a user can call explicitly. Calling a validator on
5656 a function actually written in some other language was not checked
5657 for and could be exploited for privilege-escalation purposes.
5658 The fix involves adding a call to a privilege-checking function in
5659 each validator function. Non-core procedural languages will also
5660 need to make this change to their own validator functions, if any.

5682 If the name lookups come to different conclusions due to concurrent
5683 activity, we might perform some parts of the DDL on a different table
5684 than other parts. At least in the case of <command>CREATE INDEX</>,
5685 this can be used to cause the permissions checks to be performed
5686 against a different table than the index creation, allowing for a
5687 privilege escalation attack.

5834 Rework tuple freezing protocol
5835 (Álvaro Herrera, Andres Freund)
5839 The logic for tuple freezing was unable to handle some cases involving
5841 <link linkend="vacuum-for-multixact-wraparound"><firstterm>multixact</>
5842 IDs</link>, with the practical effect that shared row-level locks
5843 might be forgotten once old enough.
5847 Fixing this required changing the WAL record format for tuple
5848 freezing. While this is no issue for standalone servers, when using
5849 replication it means that <emphasis>standby servers must be upgraded
5850 to 9.3.3 or later before their masters are</>. An older standby will
5851 be unable to interpret freeze records generated by a newer master, and
5852 will fail with a PANIC message. (In such a case, upgrading the
5853 standby should be sufficient to let it resume execution.)

5865 Create separate GUC parameters to control multixact freezing

5870 9.3 requires multixact tuple labels to be frozen before
5871 they grow too old, in the same fashion as plain transaction ID labels
5872 have been frozen for some time. Previously, the transaction ID
5873 freezing parameters were used for multixact IDs too; but since
5874 the consumption rates of transaction IDs and multixact IDs can be
5875 quite different, this did not work very well. Introduce new settings

5891 Account for remote row locks propagated by local updates
5892 (Álvaro Herrera)
5896 If a row was locked by transaction A, and transaction B updated it,
5897 the new version of the row created by B would be locked by A, yet
5898 visible only to B. If transaction B then again updated the row, A's
5899 lock wouldn't get checked, thus possibly allowing B to complete when
5900 it shouldn't. This case is new in 9.3 since prior versions did not
5901 have any types of row locking that would permit another transaction
5902 to update the row at all.
5906 This oversight could allow referential integrity checks to give false
5907 positives (for instance, allow deletes that should have been rejected).
5908 Applications using the new commands <literal>SELECT FOR KEY SHARE</>
5909 and <literal>SELECT FOR NO KEY UPDATE</> might also have suffered
5910 locking failures of this kind.

7020 <title>Release 9.3.2</title>
7023 <title>Release Date</title>
7024 <simpara>2013-12-05</simpara>
7028 This release contains a variety of fixes from 9.3.1.
7029 For information about new features in the 9.3 major release, see
7030 <xref linkend="release-9-3">.
7034 <title>Migration to Version 9.3.2</title>
7037 A dump/restore is not required for those running 9.3.X.
7041 However, this release corrects a number of potential data corruption
7042 issues. See the first three changelog entries below to find out whether
7043 your installation has been affected and what steps you can take if so.
7047 Also, if you are upgrading from a version earlier than 9.3.1,
7048 see <xref linkend="release-9-3-1">.
7054 <title>Changes</title>
7060 Fix <command>VACUUM</>'s tests to see whether it can
7061 update <structfield>relfrozenxid</> (Andres Freund)
7065 In some cases <command>VACUUM</> (either manual or autovacuum) could
7066 incorrectly advance a table's <structfield>relfrozenxid</> value,
7067 allowing tuples to escape freezing, causing those rows to become
7068 invisible once 2^31 transactions have elapsed. The probability of
7069 data loss is fairly low since multiple incorrect advancements would
7070 need to happen before actual loss occurs, but it's not zero. In 9.2.0
7071 and later, the probability of loss is higher, and it's also possible
7072 to get <quote>could not access status of transaction</> errors as a
7073 consequence of this bug. Users upgrading from releases 9.0.4 or 8.4.8
7074 or earlier are not affected, but all later versions contain the bug.
7078 The issue can be ameliorated by, after upgrading, vacuuming all tables
7079 in all databases while having <link
7080 linkend="guc-vacuum-freeze-table-age"><varname>vacuum_freeze_table_age</></link>
7081 set to zero. This will fix any latent corruption but will not be able
7082 to fix all pre-existing data errors. However, an installation can be
7083 presumed safe after performing this vacuuming if it has executed fewer
7084 than 2^31 update transactions in its lifetime (check this with
7085 <literal>SELECT txid_current() < 2^31</>).
7091 Fix multiple bugs in MultiXactId freezing (Andres Freund,
7092 Álvaro Herrera)
7096 These bugs could lead to <quote>could not access status of
7097 transaction</> errors, or to duplicate or vanishing rows.
7098 Users upgrading from releases prior to 9.3.0 are not affected.
7102 The issue can be ameliorated by, after upgrading, vacuuming all tables
7103 in all databases while having <link
7104 linkend="guc-vacuum-freeze-table-age"><varname>vacuum_freeze_table_age</></link>
7105 set to zero. This will fix latent corruption but will not be able to
7106 fix all pre-existing data errors.
7110 As a separate issue, these bugs can also cause standby servers to get
7111 out of sync with the primary, thus exhibiting data errors that are not
7112 in the primary. Therefore, it's recommended that 9.3.0 and 9.3.1
7113 standby servers be re-cloned from the primary (e.g., with a new base
7114 backup) after upgrading.
7120 Fix initialization of <filename>pg_clog</> and <filename>pg_subtrans</>
7121 during hot standby startup (Andres Freund, Heikki Linnakangas)
7125 This bug can cause data loss on standby servers at the moment they
7126 start to accept hot-standby queries, by marking committed transactions
7127 as uncommitted. The likelihood of such corruption is small unless, at
7128 the time of standby startup, the primary server has executed many
7129 updating transactions since its last checkpoint. Symptoms include
7130 missing rows, rows that should have been deleted being still visible,
7131 and obsolete versions of updated rows being still visible alongside
7132 their newer versions.
7136 This bug was introduced in versions 9.3.0, 9.2.5, 9.1.10, and 9.0.14.
7137 Standby servers that have only been running earlier releases are not
7138 at risk. It's recommended that standby servers that have ever run any
7139 of the buggy releases be re-cloned from the primary (e.g., with a new
7140 base backup) after upgrading.
7146 Fix multiple bugs in update chain traversal (Andres Freund,
7147 Álvaro Herrera)
7151 These bugs could result in incorrect behavior, such as locking or even
7152 updating the wrong row, in the presence of concurrent updates.
7153 Spurious <quote>unable to fetch updated version of tuple</> errors
7160 Fix dangling-pointer problem in fast-path locking (Tom Lane)
7164 This could lead to corruption of the lock data structures in shared
7165 memory, causing <quote>lock already held</> and other odd errors.
7171 Fix assorted race conditions in timeout management (Tom Lane)
7175 These errors could result in a server process becoming unresponsive
7176 because it had blocked SIGALRM and/or SIGINT.
7182 Truncate <filename>pg_multixact</> contents during WAL replay
7187 This avoids ever-increasing disk space consumption in standby servers.
7193 Ensure an anti-wraparound <command>VACUUM</> counts a page as scanned
7194 when it's only verified that no tuples need freezing (Sergey
7195 Burladyan, Jeff Janes)
7199 This bug could result in failing to
7200 advance <structfield>relfrozenxid</>, so that the table would still be
7201 thought to need another anti-wraparound vacuum. In the worst case the
7202 database might even shut down to prevent wraparound.
7208 Fix full-table-vacuum request mechanism for MultiXactIds (Andres Freund)
7212 This bug could result in large amounts of useless autovacuum activity.
7218 Fix race condition in GIN index posting tree page deletion (Heikki
7223 This could lead to transient wrong answers or query failures.
7229 Fix <quote>unexpected spgdoinsert() failure</> error during SP-GiST
7230 index creation (Teodor Sigaev)
7236 Fix assorted bugs in materialized views (Kevin Grittner, Andres Freund)
7242 Re-allow duplicate table aliases if they're within aliased JOINs
7247 Historically <productname>PostgreSQL</> has accepted queries like
7249 SELECT ... FROM tab1 x CROSS JOIN (tab2 x CROSS JOIN tab3 y) z
7251 although a strict reading of the SQL standard would forbid the
7252 duplicate usage of table alias <literal>x</>. A misguided change in
7253 9.3.0 caused it to reject some such cases that were formerly accepted.
7254 Restore the previous behavior.
7260 Avoid flattening a subquery whose <literal>SELECT</> list contains a
7261 volatile function wrapped inside a sub-<literal>SELECT</> (Tom Lane)
7265 This avoids unexpected results due to extra evaluations of the
7272 Fix planner's processing of non-simple-variable subquery outputs
7273 nested within outer joins (Tom Lane)
7277 This error could lead to incorrect plans for queries involving
7278 multiple levels of subqueries within <literal>JOIN</> syntax.
7284 Fix incorrect planning in cases where the same non-strict expression
7285 appears in multiple <literal>WHERE</> and outer <literal>JOIN</>
7286 equality clauses (Tom Lane)
7292 Fix planner crash with whole-row reference to a subquery (Tom Lane)
7298 Fix incorrect generation of optimized MIN()/MAX() plans for
7299 inheritance trees (Tom Lane)
7303 The planner could fail in cases where the MIN()/MAX() argument was an
7304 expression rather than a simple variable.
7310 Fix premature deletion of temporary files (Andres Freund)
7316 Prevent intra-transaction memory leak when printing range values
7321 This fix actually cures transient memory leaks in any datatype output
7322 function, but range types are the only ones known to have had a
7323 significant problem.
7329 Fix memory leaks when reloading configuration files (Heikki
7330 Linnakangas, Hari Babu)
7336 Prevent incorrect display of dropped columns in NOT NULL and CHECK
7337 constraint violation messages (Michael Paquier and Tom Lane)
7343 Allow default arguments and named-argument notation for window
7344 functions (Tom Lane)
7348 Previously, these cases were likely to crash.
7354 Suppress trailing whitespace on each line when pretty-printing rules
7355 and views (Tom Lane)
7359 9.3.0 generated such whitespace in many more cases than previous
7360 versions did. To reduce unexpected behavioral changes, suppress
7361 unnecessary whitespace in all cases.
7367 Fix possible read past end of memory in rule printing (Peter Eisentraut)
7373 Fix array slicing of <type>int2vector</> and <type>oidvector</> values
7378 Expressions of this kind are now implicitly promoted to
7379 regular <type>int2</> or <type>oid</> arrays.
7385 Return a valid JSON value when converting an empty <type>hstore</> value
7393 Fix incorrect behaviors when using a SQL-standard, simple GMT offset
7398 In some cases, the system would use the simple GMT offset value when
7399 it should have used the regular timezone setting that had prevailed
7400 before the simple offset was selected. This change also causes
7401 the <function>timeofday</> function to honor the simple GMT offset
7408 Prevent possible misbehavior when logging translations of Windows
7409 error codes (Tom Lane)
7415 Properly quote generated command lines in <application>pg_ctl</>
7416 (Naoya Anzai and Tom Lane)
7420 This fix applies only to Windows.
7426 Fix <application>pg_dumpall</> to work when a source database
7428 linkend="guc-default-transaction-read-only"><varname>default_transaction_read_only</></link>
7429 via <command>ALTER DATABASE SET</> (Kevin Grittner)
7433 Previously, the generated script would fail during restore.
7439 Fix <application>pg_isready</> to handle its <option>-d</> option
7440 properly (Fabrízio de Royes Mello and Fujii Masao)
7446 Fix parsing of WAL file names in <application>pg_receivexlog</>
7447 (Heikki Linnakangas)
7451 This error made <application>pg_receivexlog</> unable to restart
7452 streaming after stopping, once at least 4 GB of WAL had been written.
7458 Report out-of-disk-space failures properly
7459 in <application>pg_upgrade</> (Peter Eisentraut)
7465 Make <application>ecpg</> search for quoted cursor names
7466 case-sensitively (Zoltán Böszörményi)
7472 Fix <application>ecpg</>'s processing of lists of variables
7473 declared <type>varchar</> (Zoltán Böszörményi)
7479 Make <filename>contrib/lo</> defend against incorrect trigger definitions
7486 Update time zone data files to <application>tzdata</> release 2013h
7487 for DST law changes in Argentina, Brazil, Jordan, Libya,
7488 Liechtenstein, Morocco, and Palestine. Also, new timezone
7489 abbreviations WIB, WIT, WITA for Indonesia.

7682 Prevent non-key-field row updates from blocking foreign key checks
7688 Greatly reduce System V <link linkend="sysvipc">shared
7689 memory</link> requirements
7696 The above items are explained in more detail in the sections below.
7703 <title>Migration to Version 9.3</title>
7706 A dump/restore using <link
7707 linkend="APP-PG-DUMPALL"><application>pg_dumpall</></link>, or use
7708 of <link linkend="pgupgrade"><application>pg_upgrade</></link>, is
7709 required for those wishing to migrate data from any previous release.
7713 Version 9.3 contains a number of changes that may affect compatibility
7714 with previous releases. Observe the following incompatibilities:
7718 <title>Server Settings</title>
7724 Rename <varname>replication_timeout</> to <link
7725 linkend="guc-wal-sender-timeout"><varname>wal_sender_timeout</></link>
7730 This setting controls the <link
7731 linkend="wal"><acronym>WAL</></link> sender timeout.
7737 Require superuser privileges to set <link
7738 linkend="guc-commit-delay"><varname>commit_delay</></link>
7739 because it can now potentially delay other sessions (Simon Riggs)
7745 Allow in-memory sorts to use their full memory allocation (Jeff Janes)
7749 Users who have set <link
7750 linkend="guc-work-mem"><varname>work_mem</></link> based on the
7751 previous behavior may need to revisit that setting.
7760 <title>Other</title>
7766 Throw an error if a tuple to be updated or deleted has already been
7767 updated or deleted by a <literal>BEFORE</> trigger (Kevin Grittner)
7771 Formerly, the originally-intended update was silently skipped,
7772 resulting in logical inconsistency since the trigger might have
7773 propagated data to other places based on the intended update.
7774 Now an error is thrown to prevent the inconsistent results from being
7775 committed. If this change affects your application, the best solution
7776 is usually to move the data-propagation actions to
7777 an <literal>AFTER</> trigger.
7781 This error will also be thrown if a query invokes a volatile function
7782 that modifies rows that are later modified by the query itself.
7783 Such cases likewise previously resulted in silently skipping updates.
7789 Change multicolumn <link linkend="SQL-CREATETABLE"><literal>ON UPDATE
7790 SET NULL/SET DEFAULT</></link> foreign key actions to affect
7791 all columns of the constraint, not just those changed in the
7792 <command>UPDATE</> (Tom Lane)
7796 Previously, we would set only those referencing columns that
7797 correspond to referenced columns that were changed by
7798 the <command>UPDATE</>. This was what was required by SQL-92,
7799 but more recent editions of the SQL standard specify the new behavior.
7805 Force cached plans to be replanned if the <link
7806 linkend="guc-search-path"><varname>search_path</></link> changes
7811 Previously, cached plans already generated in the current session were
7812 not redone if the query was re-executed with a
7813 new <varname>search_path</> setting, resulting in surprising behavior.
7820 linkend="functions-formatting-table"><function>to_number()</></link>
7821 to properly handle a period used as a thousands separator (Tom Lane)
7825 Previously, a period was considered to be a decimal point even when
7826 the locale says it isn't and the <literal>D</> format code is used to
7827 specify use of the locale-specific decimal point. This resulted in
7828 wrong answers if <literal>FM</> format was also used.
7834 Fix <literal>STRICT</> non-set-returning functions that have
7835 set-returning functions in their arguments to properly return null
7840 A null value passed to the strict function should result in a null
7841 output, but instead, that output row was suppressed entirely.
7847 Store <link linkend="wal"><acronym>WAL</></link> in a continuous
7848 stream, rather than skipping the last 16MB segment every 4GB
7849 (Heikki Linnakangas)
7853 Previously, <acronym>WAL</> files with names ending in <literal>FF</>
7854 were not used because of this skipping. If you have <acronym>WAL</>
7855 backup or restore scripts that took this behavior into account, they
7856 will need to be adjusted.
7863 linkend="catalog-pg-constraint"><structname>pg_constraint.confmatchtype</></link>,
7864 store the default foreign key match type (non-<literal>FULL</>,
7865 non-<literal>PARTIAL</>) as <literal>s</> for <quote>simple</>
7870 Previously this case was represented by <literal>u</>
7871 for <quote>unspecified</>.
7882 <title>Changes</title>
7885 Below you will find a detailed account of the changes between
7886 <productname>PostgreSQL</productname> 9.3 and the previous major
7891 <title>Server</title>
7894 <title>Locking</title>
7900 Prevent non-key-field row updates from blocking foreign key checks
7901 (Álvaro Herrera, Noah Misch, Andres Freund, Alexander
7902 Shulgin, Marti Raudsepp, Alexander Shulgin)
7906 This change improves concurrency and reduces the probability of
7907 deadlocks when updating tables involved in a foreign-key constraint.
7908 <command>UPDATE</>s that do not change any columns referenced in a
7909 foreign key now take the new <literal>NO KEY UPDATE</> lock mode on
7910 the row, while foreign key checks use the new <literal>KEY SHARE</>
7911 lock mode, which does not conflict with <literal>NO KEY UPDATE</>.
7912 So there is no blocking unless a foreign-key column is changed.
7918 Add configuration variable <link
7919 linkend="guc-lock-timeout"><varname>lock_timeout</></link> to
7920 allow limiting how long a session will wait to acquire any one lock
7921 (Zoltán Böszörményi)
7930 <title>Indexes</title>
7936 Add <link linkend="rangetypes-indexing"><acronym>SP-GiST</></link>
7937 support for range data types (Alexander Korotkov)
7943 Allow <link linkend="GiST"><acronym>GiST</></link> indexes to be
7944 unlogged (Jeevan Chalke)
7950 Improve performance of <acronym>GiST</> index insertion by randomizing
7951 the choice of which page to descend to when there are multiple equally
7952 good alternatives (Heikki Linnakangas)
7958 Improve concurrency of hash index operations (Robert Haas)
7967 <title>Optimizer</title>
7973 Collect and use histograms of upper and lower bounds, as well as range
7974 lengths, for <link linkend="rangetypes">range types</link>
7975 (Alexander Korotkov)
7981 Improve optimizer's cost estimation for index access (Tom Lane)
7987 Improve optimizer's hash table size estimate for
7988 doing <literal>DISTINCT</> via hash aggregation (Tom Lane)
7994 Suppress no-op Result and Limit plan nodes
7995 (Kyotaro Horiguchi, Amit Kapila, Tom Lane)
8001 Reduce optimizer overhead by not keeping plans on the basis of cheap
8002 startup cost when the optimizer only cares about total cost overall
8012 <title>General Performance</title>
8018 Add <link linkend="SQL-COPY"><command>COPY FREEZE</></link>
8019 option to avoid the overhead of marking tuples as frozen later
8020 (Simon Riggs, Jeff Davis)
8026 Improve performance of <link
8027 linkend="datatype-numeric"><type>NUMERIC</></link> calculations
8034 Improve synchronization of sessions waiting for <link
8035 linkend="guc-commit-delay"><varname>commit_delay</></link>
8040 This greatly improves the usefulness of <varname>commit_delay</>.
8046 Improve performance of the <link
8047 linkend="SQL-CREATETABLE"><command>CREATE TEMPORARY TABLE ... ON
8048 COMMIT DELETE ROWS</></link> option by not truncating such temporary
8049 tables in transactions that haven't touched any temporary tables
8050 (Heikki Linnakangas)
8056 Make vacuum recheck visibility after it has removed expired tuples
8061 This increases the chance of a page being marked as all-visible.
8067 Add per-resource-owner lock caches (Jeff Janes)
8071 This speeds up lock bookkeeping at statement completion in
8072 multi-statement transactions that hold many locks; it is particularly
8073 useful for <application>pg_dump</>.
8079 Avoid scanning the entire relation cache at commit of a transaction
8080 that creates a new relation (Jeff Janes)
8084 This speeds up sessions that create many tables in successive
8085 small transactions, such as a <application>pg_restore</> run.
8091 Improve performance of transactions that drop many relations
8101 <title>Monitoring</title>
8107 Add optional ability to <link
8108 linkend="app-initdb-data-checksums">checksum</link> data pages and
8109 report corruption (Simon Riggs, Jeff Davis, Greg Smith, Ants Aasma)
8113 The checksum option can be set during <link
8114 linkend="APP-INITDB">initdb</link>.
8120 Split the <link linkend="monitoring-stats">statistics collector's</link>
8121 data file into separate global and per-database files (Tomas Vondra)
8125 This reduces the I/O required for statistics tracking.
8131 Fix the statistics collector to operate properly in cases where the
8132 system clock goes backwards (Tom Lane)
8136 Previously, statistics collection would stop until the time again
8137 reached the latest time previously recorded.
8143 Emit an informative message to postmaster standard error when we
8144 are about to stop logging there
8149 This should help reduce user confusion about where to look for log
8150 output in common configurations that log to standard error only during
8160 <title>Authentication</title>
8166 When an authentication failure occurs, log the relevant
8167 <link linkend="auth-pg-hba-conf"><filename>pg_hba.conf</></link>
8168 line, to ease debugging of unintended failures
8175 Improve <link linkend="auth-ldap"><acronym>LDAP</></link> error
8176 reporting and documentation (Peter Eisentraut)
8182 Add support for specifying <acronym>LDAP</> authentication parameters
8183 in <acronym>URL</> format, per RFC 4516 (Peter Eisentraut)
8190 linkend="guc-ssl-ciphers"><varname>ssl_ciphers</></link> parameter
8191 to start with <literal>DEFAULT</>, rather than <literal>ALL</>,
8192 then remove insecure ciphers (Magnus Hagander)
8196 This should yield a more appropriate SSL cipher set.
8202 Parse and load <link
8203 linkend="auth-username-maps"><filename>pg_ident.conf</></link>
8204 once, not during each connection (Amit Kapila)
8208 This is similar to how <filename>pg_hba.conf</> is processed.
8217 <title>Server Settings</title>
8223 Greatly reduce System V <link linkend="sysvipc">shared
8224 memory</link> requirements (Robert Haas)
8228 On Unix-like systems, <function>mmap()</> is now used for most
8229 of <productname>PostgreSQL</>'s shared memory. For most users, this
8230 will eliminate any need to adjust kernel parameters for shared memory.
8236 Allow the postmaster to listen on multiple Unix-domain sockets
8237 (Honza Horák)
8241 The configuration parameter
8242 <varname>unix_socket_directory</> is replaced by <link
8243 linkend="guc-unix-socket-directories"><varname>unix_socket_directories</></link>,
8244 which accepts a list of directories.
8250 Allow a directory of configuration files to be processed (Magnus
8251 Hagander, Greg Smith, Selena Deckelmann)
8255 Such a directory is specified with <link
8256 linkend="config-includes"><varname>include_dir</></link> in the server
8263 Increase the maximum <link
8264 linkend="APP-INITDB">initdb</link>-configured value for <link
8265 linkend="guc-shared-buffers"><varname>shared_buffers</></link>
8266 to 128MB (Robert Haas)
8270 This is the maximum value that initdb will attempt to set in <link
8271 linkend="config-setting-configuration-file"><filename>postgresql.conf</></link>;
8272 the previous maximum was 32MB.
8278 Remove the <link linkend="guc-external-pid-file">external
8279 <acronym>PID</> file</link>, if any, on postmaster exit
8291 <title>Replication and Recovery</title>
8297 Allow a streaming replication standby to <link
8298 linkend="protocol-replication">follow a timeline switch</link>
8299 (Heikki Linnakangas)
8303 This allows streaming standby servers to receive WAL data from a slave
8304 newly promoted to master status. Previously, other standbys would
8305 require a resync to begin following the new master.
8311 Add <acronym>SQL</> functions <link
8312 linkend="functions-admin-backup"><function>pg_is_in_backup()</></link>
8314 linkend="functions-admin-backup"><function>pg_backup_start_time()</></link>
8319 These functions report the status of base backups.
8325 Improve performance of streaming log shipping with <link
8326 linkend="guc-synchronous-commit"><varname>synchronous_commit</></link>
8327 disabled (Andres Freund)
8333 Allow much faster promotion of a streaming standby to primary (Simon
8334 Riggs, Kyotaro Horiguchi)
8340 Add the last checkpoint's redo location to <link
8341 linkend="APP-PGCONTROLDATA"><application>pg_controldata</></link>'s
8342 output (Fujii Masao)
8346 This information is useful for determining which <acronym>WAL</>
8347 files are needed for restore.
8353 Allow tools like <link
8354 linkend="app-pgreceivexlog"><application>pg_receivexlog</></link>
8355 to run on computers with different architectures (Heikki
8360 WAL files can still only be replayed on servers with the same
8361 architecture as the primary; but they can now be transmitted to and
8362 stored on machines of any architecture, since the
8363 streaming replication protocol is now machine-independent.
8370 linkend="app-pgbasebackup"><application>pg_basebackup</></link>
8371 <option>--write-recovery-conf</> output a
8372 minimal <filename>recovery.conf</> file (Zoltán
8373 Böszörményi, Magnus Hagander)
8377 This simplifies setting up a standby server.
8384 linkend="app-pgreceivexlog"><application>pg_receivexlog</></link>
8386 linkend="app-pgbasebackup"><application>pg_basebackup</></link>
8387 <option>--xlog-method</> to handle streaming timeline switches
8388 (Heikki Linnakangas)
8395 linkend="guc-wal-receiver-timeout"><varname>wal_receiver_timeout</></link>
8396 parameter to control the <acronym>WAL</> receiver's timeout
8401 This allows more rapid detection of connection failure.
8407 Change the <link linkend="wal"><acronym>WAL</></link> record format to
8408 allow splitting the record header across pages (Heikki Linnakangas)
8412 The new format is slightly more compact, and is more efficient to
8422 <title>Queries</title>
8428 Implement <acronym>SQL</>-standard <link
8429 linkend="queries-lateral"><literal>LATERAL</></link> option for
8430 <literal>FROM</>-clause subqueries and function calls (Tom Lane)
8434 This feature allows subqueries and functions in <literal>FROM</> to
8435 reference columns from other tables in the <literal>FROM</>
8436 clause. The <literal>LATERAL</> keyword is optional for functions.
8442 Add support for piping <link
8443 linkend="SQL-COPY"><command>COPY</></link> and <link
8444 linkend="APP-PSQL"><application>psql</></link> <command>\copy</>
8445 data to/from an external program (Etsuro Fujita)
8451 Allow a multirow <link
8452 linkend="SQL-VALUES"><literal>VALUES</></link> clause in a rule
8453 to reference <literal>OLD</>/<literal>NEW</> (Tom Lane)
8462 <title>Object Manipulation</title>
8468 Add support for <link linkend="event-triggers">event triggers</link>
8469 (Dimitri Fontaine, Robert Haas, Álvaro Herrera)
8473 This allows server-side functions written in event-enabled
8474 languages to be called when DDL commands are run.
8480 Allow <link linkend="SQL-CREATEFOREIGNDATAWRAPPER">foreign data
8481 wrappers</link> to support writes (inserts/updates/deletes) on foreign
8482 tables (KaiGai Kohei)
8488 Add <link linkend="SQL-CREATESCHEMA"><command>CREATE SCHEMA ... IF
8489 NOT EXISTS</></link> clause (Fabrízio de Royes Mello)
8495 Make <link linkend="SQL-REASSIGN-OWNED"><command>REASSIGN
8496 OWNED</></link> also change ownership of shared objects
8497 (Álvaro Herrera)
8503 Make <link linkend="sql-createaggregate"><command>CREATE
8504 AGGREGATE</></link> complain if the given initial value string is not
8505 valid input for the transition datatype (Tom Lane)
8511 Suppress <link linkend="SQL-CREATETABLE"><command>CREATE
8512 TABLE</></link>'s messages about implicit index and sequence creation
8517 These messages now appear at <literal>DEBUG1</> verbosity, so that
8518 they will not be shown by default.
8524 Allow <link linkend="SQL-DROPTABLE"><command>DROP TABLE IF
8525 EXISTS</></link> to succeed when a non-existent schema is specified
8526 in the table name (Bruce Momjian)
8530 Previously, it threw an error if the schema did not exist.
8536 Provide clients with <link
8537 linkend="libpq-pqresulterrorfield">constraint violation details</link>
8538 as separate fields (Pavel Stehule)
8542 This allows clients to retrieve table, column, data type, or
8543 constraint name error details. Previously such information had to be
8544 extracted from error strings. Client library support is required to
8545 access these fields.
8552 <title><command>ALTER</></title>
8558 Support <literal>IF NOT EXISTS</> option in <link
8559 linkend="SQL-ALTERTYPE"><command>ALTER TYPE ... ADD VALUE</></link>
8564 This is useful for conditionally adding values to enumerated types.
8570 Add <link linkend="SQL-ALTERROLE"><command>ALTER ROLE ALL
8571 SET</></link> to establish settings for all users (Peter Eisentraut)
8575 This allows settings to apply to all users in all databases. <link

8600 Add <link linkend="SQL-CREATEMATERIALIZEDVIEW">materialized
8601 views</link> (Kevin Grittner)
8605 Unlike ordinary views, where the base tables are read on every access,
8606 materialized views create physical tables at creation or refresh time.
8607 Access to the materialized view then reads from its physical
8608 table. There is not yet any facility for incrementally refreshing
8609 materialized views or auto-accessing them via base table access.
8615 Make simple views <link
8616 linkend="SQL-CREATEVIEW-updatable-views">auto-updatable</link>
8621 Simple views that reference some or all columns from a
8622 single base table are now updatable by default. More
8623 complex views can be made updatable using <link
8624 linkend="SQL-CREATETRIGGER"><literal>INSTEAD OF</></link> triggers
8625 or <link linkend="SQL-CREATERULE"><literal>INSTEAD</></link> rules.

8636 Internally this is translated into <command>CREATE VIEW ... WITH
8643 Improve view/rule printing code to handle cases where referenced
8644 tables are renamed, or columns are renamed, added, or dropped
8649 Table and column renamings can produce cases where, if we merely
8650 substitute the new name into the original text of a rule or view, the
8651 result is ambiguous. This change fixes the rule-dumping code to insert
8652 manufactured table and column aliases when needed to preserve the

8670 Increase the maximum size of <link linkend="largeObjects">large
8671 objects</link> from 2GB to 4TB (Nozomi Anzai, Yugo Nagata)
8675 This change includes adding 64-bit-capable large object access
8676 functions, both in the server and in libpq.
8682 Allow text <link linkend="datatype-timezones">timezone

8887 Add PL/Python result object string handler (Peter Eisentraut)
8891 This allows <literal>plpy.debug(rv)</literal> to output something reasonable.

8904 Handle <link linkend="spi"><acronym>SPI</></link> errors raised
8905 explicitly (with PL/Python's <literal>RAISE</>) the same as

8917 <title>Server Programming Interface (<link linkend="spi">SPI</link>)</title>
8923 Prevent leakage of <acronym>SPI</> tuple tables during subtransaction
8928 At the end of any failed subtransaction, the core SPI code now
8929 releases any SPI tuple tables that were created during that
8930 subtransaction. This avoids the need for SPI-using code to keep track
8931 of such tuple tables and release them manually in error-recovery code.
8932 Failure to do so caused a number of transaction-lifespan memory leakage
8933 issues in PL/pgSQL and perhaps other SPI clients. <link
8934 linkend="spi-spi-freetupletable"><function>SPI_freetuptable()</></link>
8935 now protects itself against multiple freeing requests, so any existing
8936 code that did take care to clean up shouldn't be broken by this change.
