8 <title>Release Date</title>
9 <simpara>2014-07-24</simpara>
13 This release contains a variety of fixes from 9.3.4.
14 For information about new features in the 9.3 major release, see
15 <xref linkend="release-9-3">.
19 <title>Migration to Version 9.3.5</title>
22 A dump/restore is not required for those running 9.3.X.
26 However, this release corrects a logic error
27 in <application>pg_upgrade</>, as well as an index corruption problem in
28 some GiST indexes. See the first two changelog entries below to find out
29 whether your installation has been affected and what steps you should take
34 Also, if you are upgrading from a version earlier than 9.3.4,
35 see <xref linkend="release-9-3-4">.

54 In <application>pg_upgrade</>, remove <filename>pg_multixact</> files
55 left behind by <application>initdb</> (Bruce Momjian)
59 If you used a pre-9.3.5 version of <application>pg_upgrade</> to
60 upgrade a database cluster to 9.3, it might have left behind a file
61 <filename>$PGDATA/pg_multixact/offsets/0000</> that should not be
62 there and will eventually cause problems in <command>VACUUM</>.
63 <emphasis>However, in common cases this file is actually valid and
64 must not be removed.</emphasis>
65 To determine whether your installation has this problem, run this
66 query as superuser, in any database of the cluster:
68 WITH list(file) AS (SELECT * FROM pg_ls_dir('pg_multixact/offsets'))
69 SELECT EXISTS (SELECT * FROM list WHERE file = '0000') AND
70 NOT EXISTS (SELECT * FROM list WHERE file = '0001') AND
71 NOT EXISTS (SELECT * FROM list WHERE file = 'FFFF') AND
72 EXISTS (SELECT * FROM list WHERE file != '0000')
73 AS file_0000_removal_required;
75 If this query returns <literal>t</>, manually remove the file
76 <filename>$PGDATA/pg_multixact/offsets/0000</>.
77 Do nothing if the query returns <literal>f</>.

320 Ensure that the planner sees equivalent <literal>VARIADIC</> and
321 non-<literal>VARIADIC</> function calls as equivalent (Tom Lane)
325 This bug could for example result in failure to use expression indexes
326 involving variadic functions. It might be necessary to re-create such
327 indexes, and/or re-create views including variadic function calls that
328 should match the indexes, for the fix to be effective for existing 9.3

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

712 Secure Unix-domain sockets of temporary postmasters started during
713 <literal>make check</> (Noah Misch)
717 Any local user able to access the socket file could connect as the
718 server's bootstrap superuser, then proceed to execute arbitrary code as
719 the operating-system user running the test, as we previously noted in
720 CVE-2014-0067. This change defends against that risk by placing the
721 server's socket in a temporary, mode 0700 subdirectory
722 of <filename>/tmp</>. The hazard remains however on platforms where
723 Unix sockets are not supported, notably Windows, because then the
724 temporary postmaster must accept local TCP connections.
728 A useful side effect of this change is to simplify
729 <literal>make check</> testing in builds that
730 override <literal>DEFAULT_PGSOCKET_DIR</>. Popular non-default values
731 like <filename>/var/run/postgresql</> are often not writable by the
732 build user, requiring workarounds that will no longer be necessary.

1139 <title>Migration to Version 9.3.4</title>
1142 A dump/restore is not required for those running 9.3.X.
1146 However, the error fixed in the first changelog entry below could have
1147 resulted in corrupt data on standby servers. It may be prudent to
1148 reinitialize standby servers from fresh base backups after installing

1172 Fix WAL replay of locking an already-updated tuple (Andres Freund,
1173 Álvaro Herrera)
1177 This error caused updated rows to not be found by index scans, resulting
1178 in inconsistent query results depending on whether an index scan was
1179 used. Subsequent processing could result in constraint violations,
1180 since the previously updated row would not be found by later index
1181 searches, thus possibly allowing conflicting rows to be inserted.
1182 Since this error is in WAL replay, it would only manifest during crash
1183 recovery or on standby servers. The improperly-replayed case most
1184 commonly arises when a table row that is referenced by a foreign-key
1185 constraint is updated concurrently with creation of a referencing row.

1542 but it could also fail with errors from the remote server, or worse
1543 give silently wrong answers.

1590 <title>Release Date</title>
1591 <simpara>2014-02-20</simpara>
1595 This release contains a variety of fixes from 9.3.2.
1596 For information about new features in the 9.3 major release, see
1597 <xref linkend="release-9-3">.
1601 <title>Migration to Version 9.3.3</title>
1604 A dump/restore is not required for those running 9.3.X.
1608 However, several of the issues corrected in this release could have
1609 resulted in corruption of foreign-key constraints; that is, there
1610 might now be referencing rows for which there is no matching row in
1611 the referenced table. It may be worthwhile to recheck such
1612 constraints after installing this update. The simplest way to do that
1613 is to drop and recreate each suspect constraint; however, that will
1614 require taking an exclusive lock on both tables, so it is unlikely to
1615 be acceptable in production databases. Alternatively, you can do a
1616 manual join query between the two tables to look for unmatched rows.
1620 Note also the requirement for replication standby servers to be
1621 upgraded before their master server is upgraded.
1625 Also, if you are upgrading from a version earlier than 9.3.2,
1626 see <xref linkend="release-9-3-2">.

1648 Shore up <literal>GRANT ... WITH ADMIN OPTION</> restrictions
1653 Granting a role without <literal>ADMIN OPTION</> is supposed to
1654 prevent the grantee from adding or removing members from the granted
1655 role, but this restriction was easily bypassed by doing <literal>SET
1656 ROLE</> first. The security impact is mostly that a role member can
1657 revoke the access of others, contrary to the wishes of his grantor.
1658 Unapproved role member additions are a lesser concern, since an
1659 uncooperative role member could provide most of his rights to others
1660 anyway by creating views or <literal>SECURITY DEFINER</> functions.

1677 Prevent privilege escalation via manual calls to PL validator
1678 functions (Andres Freund)
1682 The primary role of PL validator functions is to be called implicitly
1683 during <command>CREATE FUNCTION</>, but they are also normal SQL
1684 functions that a user can call explicitly. Calling a validator on
1685 a function actually written in some other language was not checked
1686 for and could be exploited for privilege-escalation purposes.
1687 The fix involves adding a call to a privilege-checking function in
1688 each validator function. Non-core procedural languages will also
1689 need to make this change to their own validator functions, if any.

1706 Avoid multiple name lookups during table and index DDL
1707 (Robert Haas, Andres Freund)
1711 If the name lookups come to different conclusions due to concurrent
1712 activity, we might perform some parts of the DDL on a different table
1713 than other parts. At least in the case of <command>CREATE INDEX</>,
1714 this can be used to cause the permissions checks to be performed
1715 against a different table than the index creation, allowing for a
1716 privilege escalation attack.

1733 Prevent buffer overrun with long datetime strings (Noah Misch)
1737 The <literal>MAXDATELEN</> constant was too small for the longest
1738 possible value of type <type>interval</>, allowing a buffer overrun
1739 in <function>interval_out()</>. Although the datetime input
1740 functions were more careful about avoiding buffer overrun, the limit
1741 was short enough to cause them to reject some valid inputs, such as
1742 input containing a very long timezone name. The <application>ecpg</>
1743 library contained these vulnerabilities along with some of its own.

1761 (Noah Misch, Heikki Linnakangas)
1765 Several functions, mostly type input functions, calculated an
1766 allocation size without checking for overflow. If overflow did
1767 occur, a too-small buffer would be allocated and then written past.

1790 guarantee that fixed-size buffers are not overrun. Unlike the
1791 preceding items, it is unclear whether these cases really represent
1792 live issues, since in most cases there appear to be previous
1793 constraints on the size of the input string. Nonetheless it seems
1794 prudent to silence all Coverity warnings of this type.

1837 Document risks of <literal>make check</> in the regression testing
1838 instructions (Noah Misch, Tom Lane)
1842 Since the temporary server started by <literal>make check</>
1843 uses <quote>trust</> authentication, another user on the same machine
1844 could connect to it as database superuser, and then potentially
1845 exploit the privileges of the operating-system user who started the
1846 tests. A future release will probably incorporate changes in the
1847 testing procedure to prevent this risk, but some public discussion is
1848 needed first. So for the moment, just warn people against using

1863 Rework tuple freezing protocol
1864 (Álvaro Herrera, Andres Freund)
1868 The logic for tuple freezing was unable to handle some cases involving
1870 <link linkend="vacuum-for-multixact-wraparound"><firstterm>multixact</>
1871 IDs</link>, with the practical effect that shared row-level locks
1872 might be forgotten once old enough.
1876 Fixing this required changing the WAL record format for tuple
1877 freezing. While this is no issue for standalone servers, when using
1878 replication it means that <emphasis>standby servers must be upgraded
1879 to 9.3.3 or later before their masters are</>. An older standby will
1880 be unable to interpret freeze records generated by a newer master, and
1881 will fail with a PANIC message. (In such a case, upgrading the
1882 standby should be sufficient to let it resume execution.)

1894 Create separate GUC parameters to control multixact freezing
1895 (Álvaro Herrera)
1899 9.3 requires multixact tuple labels to be frozen before
1900 they grow too old, in the same fashion as plain transaction ID labels
1901 have been frozen for some time. Previously, the transaction ID
1902 freezing parameters were used for multixact IDs too; but since
1903 the consumption rates of transaction IDs and multixact IDs can be
1904 quite different, this did not work very well. Introduce new settings
1905 <xref linkend="guc-vacuum-multixact-freeze-min-age">,

1920 Account for remote row locks propagated by local updates
1921 (Álvaro Herrera)
1925 If a row was locked by transaction A, and transaction B updated it,
1926 the new version of the row created by B would be locked by A, yet
1927 visible only to B. If transaction B then again updated the row, A's
1928 lock wouldn't get checked, thus possibly allowing B to complete when
1929 it shouldn't. This case is new in 9.3 since prior versions did not
1930 have any types of row locking that would permit another transaction
1931 to update the row at all.
1935 This oversight could allow referential integrity checks to give false
1936 positives (for instance, allow deletes that should have been rejected).
1937 Applications using the new commands <literal>SELECT FOR KEY SHARE</>
1938 and <literal>SELECT FOR NO KEY UPDATE</> might also have suffered
1939 locking failures of this kind.

2076 Fix possible mis-replay of WAL records when some segments of a
2077 relation aren't full size (Greg Stark, Tom Lane)
2081 The WAL update could be applied to the wrong page, potentially many
2082 pages past where it should have been. Aside from corrupting data,
2083 this error has been observed to result in significant <quote>bloat</>
2084 of standby servers compared to their masters, due to updates being
2085 applied far beyond where the end-of-file should have been. This
2086 failure mode does not appear to be a significant risk during crash
2087 recovery, only when initially synchronizing a standby created from a
2088 base backup taken from a quickly-changing master.

3009 These text files duplicated the main HTML and PDF documentation
3010 formats. The trouble involved in maintaining them greatly outweighs
3011 the likely audience for plain-text format. Distribution tarballs
3012 will still contain files by these names, but they'll just be stubs
3013 directing the reader to consult the main documentation.
3014 The plain-text <filename>INSTALL</> file will still be maintained, as
3015 there is arguably a use-case for that.

3058 For information about new features in the 9.3 major release, see
3059 <xref linkend="release-9-3">.
3063 <title>Migration to Version 9.3.2</title>
3066 A dump/restore is not required for those running 9.3.X.
3070 However, this release corrects a number of potential data corruption
3071 issues. See the first three changelog entries below to find out whether
3072 your installation has been affected and what steps you can take if so.
3076 Also, if you are upgrading from a version earlier than 9.3.1,
3077 see <xref linkend="release-9-3-1">.
3083 <title>Changes</title>
3089 Fix <command>VACUUM</>'s tests to see whether it can
3090 update <structfield>relfrozenxid</> (Andres Freund)
3094 In some cases <command>VACUUM</> (either manual or autovacuum) could
3095 incorrectly advance a table's <structfield>relfrozenxid</> value,
3096 allowing tuples to escape freezing, causing those rows to become
3097 invisible once 2^31 transactions have elapsed. The probability of
3098 data loss is fairly low since multiple incorrect advancements would
3099 need to happen before actual loss occurs, but it's not zero. In 9.2.0
3100 and later, the probability of loss is higher, and it's also possible
3101 to get <quote>could not access status of transaction</> errors as a
3102 consequence of this bug. Users upgrading from releases 9.0.4 or 8.4.8
3103 or earlier are not affected, but all later versions contain the bug.
3107 The issue can be ameliorated by, after upgrading, vacuuming all tables
3108 in all databases while having <link
3109 linkend="guc-vacuum-freeze-table-age"><varname>vacuum_freeze_table_age</></link>
3110 set to zero. This will fix any latent corruption but will not be able
3111 to fix all pre-existing data errors. However, an installation can be
3112 presumed safe after performing this vacuuming if it has executed fewer
3113 than 2^31 update transactions in its lifetime (check this with
3114 <literal>SELECT txid_current() < 2^31</>).
3120 Fix multiple bugs in MultiXactId freezing (Andres Freund,
3121 Álvaro Herrera)
3125 These bugs could lead to <quote>could not access status of
3126 transaction</> errors, or to duplicate or vanishing rows.
3127 Users upgrading from releases prior to 9.3.0 are not affected.
3131 The issue can be ameliorated by, after upgrading, vacuuming all tables
3132 in all databases while having <link
3133 linkend="guc-vacuum-freeze-table-age"><varname>vacuum_freeze_table_age</></link>
3134 set to zero. This will fix latent corruption but will not be able to
3135 fix all pre-existing data errors.
3139 As a separate issue, these bugs can also cause standby servers to get
3140 out of sync with the primary, thus exhibiting data errors that are not
3141 in the primary. Therefore, it's recommended that 9.3.0 and 9.3.1
3142 standby servers be re-cloned from the primary (e.g., with a new base
3143 backup) after upgrading.
3149 Fix initialization of <filename>pg_clog</> and <filename>pg_subtrans</>
3150 during hot standby startup (Andres Freund, Heikki Linnakangas)
3154 This bug can cause data loss on standby servers at the moment they
3155 start to accept hot-standby queries, by marking committed transactions
3156 as uncommitted. The likelihood of such corruption is small unless, at
3157 the time of standby startup, the primary server has executed many
3158 updating transactions since its last checkpoint. Symptoms include
3159 missing rows, rows that should have been deleted being still visible,
3160 and obsolete versions of updated rows being still visible alongside
3161 their newer versions.
3165 This bug was introduced in versions 9.3.0, 9.2.5, 9.1.10, and 9.0.14.
3166 Standby servers that have only been running earlier releases are not
3167 at risk. It's recommended that standby servers that have ever run any
3168 of the buggy releases be re-cloned from the primary (e.g., with a new
3169 base backup) after upgrading.
3175 Fix multiple bugs in update chain traversal (Andres Freund,
3176 Álvaro Herrera)
3180 These bugs could result in incorrect behavior, such as locking or even
3181 updating the wrong row, in the presence of concurrent updates.
3182 Spurious <quote>unable to fetch updated version of tuple</> errors
3189 Fix dangling-pointer problem in fast-path locking (Tom Lane)
3193 This could lead to corruption of the lock data structures in shared
3194 memory, causing <quote>lock already held</> and other odd errors.
3200 Fix assorted race conditions in timeout management (Tom Lane)
3204 These errors could result in a server process becoming unresponsive
3205 because it had blocked SIGALRM and/or SIGINT.
3211 Truncate <filename>pg_multixact</> contents during WAL replay
3216 This avoids ever-increasing disk space consumption in standby servers.
3222 Ensure an anti-wraparound <command>VACUUM</> counts a page as scanned
3223 when it's only verified that no tuples need freezing (Sergey
3224 Burladyan, Jeff Janes)
3228 This bug could result in failing to
3229 advance <structfield>relfrozenxid</>, so that the table would still be
3230 thought to need another anti-wraparound vacuum. In the worst case the
3231 database might even shut down to prevent wraparound.
3237 Fix full-table-vacuum request mechanism for MultiXactIds (Andres Freund)
3241 This bug could result in large amounts of useless autovacuum activity.
3247 Fix race condition in GIN index posting tree page deletion (Heikki
3252 This could lead to transient wrong answers or query failures.
3258 Fix <quote>unexpected spgdoinsert() failure</> error during SP-GiST
3259 index creation (Teodor Sigaev)
3265 Fix assorted bugs in materialized views (Kevin Grittner, Andres Freund)
3271 Re-allow duplicate table aliases if they're within aliased JOINs
3276 Historically <productname>PostgreSQL</> has accepted queries like
3278 SELECT ... FROM tab1 x CROSS JOIN (tab2 x CROSS JOIN tab3 y) z
3280 although a strict reading of the SQL standard would forbid the
3281 duplicate usage of table alias <literal>x</>. A misguided change in
3282 9.3.0 caused it to reject some such cases that were formerly accepted.
3283 Restore the previous behavior.
3289 Avoid flattening a subquery whose <literal>SELECT</> list contains a
3290 volatile function wrapped inside a sub-<literal>SELECT</> (Tom Lane)
3294 This avoids unexpected results due to extra evaluations of the
3301 Fix planner's processing of non-simple-variable subquery outputs
3302 nested within outer joins (Tom Lane)
3306 This error could lead to incorrect plans for queries involving
3307 multiple levels of subqueries within <literal>JOIN</> syntax.
3313 Fix incorrect planning in cases where the same non-strict expression
3314 appears in multiple <literal>WHERE</> and outer <literal>JOIN</>
3315 equality clauses (Tom Lane)
3321 Fix planner crash with whole-row reference to a subquery (Tom Lane)
3327 Fix incorrect generation of optimized MIN()/MAX() plans for
3328 inheritance trees (Tom Lane)
3332 The planner could fail in cases where the MIN()/MAX() argument was an
3333 expression rather than a simple variable.
3339 Fix premature deletion of temporary files (Andres Freund)
3345 Prevent intra-transaction memory leak when printing range values
3350 This fix actually cures transient memory leaks in any datatype output
3351 function, but range types are the only ones known to have had a
3352 significant problem.
3358 Fix memory leaks when reloading configuration files (Heikki
3359 Linnakangas, Hari Babu)
3365 Prevent incorrect display of dropped columns in NOT NULL and CHECK
3366 constraint violation messages (Michael Paquier and Tom Lane)
3372 Allow default arguments and named-argument notation for window
3373 functions (Tom Lane)
3377 Previously, these cases were likely to crash.
3383 Suppress trailing whitespace on each line when pretty-printing rules
3384 and views (Tom Lane)
3388 9.3.0 generated such whitespace in many more cases than previous
3389 versions did. To reduce unexpected behavioral changes, suppress
3390 unnecessary whitespace in all cases.
3396 Fix possible read past end of memory in rule printing (Peter Eisentraut)
3402 Fix array slicing of <type>int2vector</> and <type>oidvector</> values
3407 Expressions of this kind are now implicitly promoted to
3408 regular <type>int2</> or <type>oid</> arrays.
3414 Return a valid JSON value when converting an empty <type>hstore</> value
3422 Fix incorrect behaviors when using a SQL-standard, simple GMT offset
3427 In some cases, the system would use the simple GMT offset value when
3428 it should have used the regular timezone setting that had prevailed
3429 before the simple offset was selected. This change also causes
3430 the <function>timeofday</> function to honor the simple GMT offset
3437 Prevent possible misbehavior when logging translations of Windows
3438 error codes (Tom Lane)
3444 Properly quote generated command lines in <application>pg_ctl</>
3445 (Naoya Anzai and Tom Lane)
3449 This fix applies only to Windows.
3455 Fix <application>pg_dumpall</> to work when a source database
3457 linkend="guc-default-transaction-read-only"><varname>default_transaction_read_only</></link>
3458 via <command>ALTER DATABASE SET</> (Kevin Grittner)
3462 Previously, the generated script would fail during restore.
3468 Fix <application>pg_isready</> to handle its <option>-d</> option
3469 properly (Fabrízio de Royes Mello and Fujii Masao)
3475 Fix parsing of WAL file names in <application>pg_receivexlog</>
3476 (Heikki Linnakangas)
3480 This error made <application>pg_receivexlog</> unable to restart
3481 streaming after stopping, once at least 4 GB of WAL had been written.
3487 Report out-of-disk-space failures properly
3488 in <application>pg_upgrade</> (Peter Eisentraut)
3494 Make <application>ecpg</> search for quoted cursor names
3495 case-sensitively (Zoltán Böszörményi)
3501 Fix <application>ecpg</>'s processing of lists of variables
3502 declared <type>varchar</> (Zoltán Böszörményi)
3508 Make <filename>contrib/lo</> defend against incorrect trigger definitions
3515 Update time zone data files to <application>tzdata</> release 2013h
3516 for DST law changes in Argentina, Brazil, Jordan, Libya,
3517 Liechtenstein, Morocco, and Palestine. Also, new timezone
3518 abbreviations WIB, WIT, WITA for Indonesia.

3717 Greatly reduce System V <link linkend="sysvipc">shared
3718 memory</link> requirements
3725 The above items are explained in more detail in the sections below.
3732 <title>Migration to Version 9.3</title>
3735 A dump/restore using <link
3736 linkend="APP-PG-DUMPALL"><application>pg_dumpall</></link>, or use
3737 of <link linkend="pgupgrade"><application>pg_upgrade</></link>, is
3738 required for those wishing to migrate data from any previous release.
3742 Version 9.3 contains a number of changes that may affect compatibility
3743 with previous releases. Observe the following incompatibilities:
3747 <title>Server Settings</title>
3753 Rename <varname>replication_timeout</> to <link
3754 linkend="guc-wal-sender-timeout"><varname>wal_sender_timeout</></link>
3759 This setting controls the <link
3760 linkend="wal"><acronym>WAL</></link> sender timeout.
3766 Require superuser privileges to set <link
3767 linkend="guc-commit-delay"><varname>commit_delay</></link>
3768 because it can now potentially delay other sessions (Simon Riggs)
3774 Allow in-memory sorts to use their full memory allocation (Jeff Janes)
3778 Users who have set <link
3779 linkend="guc-work-mem"><varname>work_mem</></link> based on the
3780 previous behavior may need to revisit that setting.
3789 <title>Other</title>
3795 Throw an error if a tuple to be updated or deleted has already been
3796 updated or deleted by a <literal>BEFORE</> trigger (Kevin Grittner)
3800 Formerly, the originally-intended update was silently skipped,
3801 resulting in logical inconsistency since the trigger might have
3802 propagated data to other places based on the intended update.
3803 Now an error is thrown to prevent the inconsistent results from being
3804 committed. If this change affects your application, the best solution
3805 is usually to move the data-propagation actions to
3806 an <literal>AFTER</> trigger.
3810 This error will also be thrown if a query invokes a volatile function
3811 that modifies rows that are later modified by the query itself.
3812 Such cases likewise previously resulted in silently skipping updates.
3818 Change multicolumn <link linkend="SQL-CREATETABLE"><literal>ON UPDATE
3819 SET NULL/SET DEFAULT</></link> foreign key actions to affect
3820 all columns of the constraint, not just those changed in the
3821 <command>UPDATE</> (Tom Lane)
3825 Previously, we would set only those referencing columns that
3826 correspond to referenced columns that were changed by
3827 the <command>UPDATE</>. This was what was required by SQL-92,
3828 but more recent editions of the SQL standard specify the new behavior.
3834 Force cached plans to be replanned if the <link
3835 linkend="guc-search-path"><varname>search_path</></link> changes
3840 Previously, cached plans already generated in the current session were
3841 not redone if the query was re-executed with a
3842 new <varname>search_path</> setting, resulting in surprising behavior.
3849 linkend="functions-formatting-table"><function>to_number()</></link>
3850 to properly handle a period used as a thousands separator (Tom Lane)
3854 Previously, a period was considered to be a decimal point even when
3855 the locale says it isn't and the <literal>D</> format code is used to
3856 specify use of the locale-specific decimal point. This resulted in
3857 wrong answers if <literal>FM</> format was also used.
3863 Fix <literal>STRICT</> non-set-returning functions that have
3864 set-returning functions in their arguments to properly return null
3869 A null value passed to the strict function should result in a null
3870 output, but instead, that output row was suppressed entirely.
3876 Store <link linkend="wal"><acronym>WAL</></link> in a continuous
3877 stream, rather than skipping the last 16MB segment every 4GB
3878 (Heikki Linnakangas)
3882 Previously, <acronym>WAL</> files with names ending in <literal>FF</>
3883 were not used because of this skipping. If you have <acronym>WAL</>
3884 backup or restore scripts that took this behavior into account, they
3885 will need to be adjusted.
3892 linkend="catalog-pg-constraint"><structname>pg_constraint.confmatchtype</></link>,
3893 store the default foreign key match type (non-<literal>FULL</>,
3894 non-<literal>PARTIAL</>) as <literal>s</> for <quote>simple</>
3899 Previously this case was represented by <literal>u</>
3900 for <quote>unspecified</>.
3911 <title>Changes</title>
3914 Below you will find a detailed account of the changes between
3915 <productname>PostgreSQL</productname> 9.3 and the previous major
3920 <title>Server</title>
3923 <title>Locking</title>
3929 Prevent non-key-field row updates from blocking foreign key checks
3930 (Álvaro Herrera, Noah Misch, Andres Freund, Alexander
3931 Shulgin, Marti Raudsepp, Alexander Shulgin)
3935 This change improves concurrency and reduces the probability of
3936 deadlocks when updating tables involved in a foreign-key constraint.
3937 <command>UPDATE</>s that do not change any columns referenced in a
3938 foreign key now take the new <literal>NO KEY UPDATE</> lock mode on
3939 the row, while foreign key checks use the new <literal>KEY SHARE</>
3940 lock mode, which does not conflict with <literal>NO KEY UPDATE</>.
3941 So there is no blocking unless a foreign-key column is changed.
3947 Add configuration variable <link
3948 linkend="guc-lock-timeout"><varname>lock_timeout</></link> to
3949 allow limiting how long a session will wait to acquire any one lock
3950 (Zoltán Böszörményi)
3959 <title>Indexes</title>
3965 Add <link linkend="rangetypes-indexing"><acronym>SP-GiST</></link>
3966 support for range data types (Alexander Korotkov)
3972 Allow <link linkend="GiST"><acronym>GiST</></link> indexes to be
3973 unlogged (Jeevan Chalke)
3979 Improve performance of <acronym>GiST</> index insertion by randomizing
3980 the choice of which page to descend to when there are multiple equally
3981 good alternatives (Heikki Linnakangas)
3987 Improve concurrency of hash index operations (Robert Haas)
3996 <title>Optimizer</title>
4002 Collect and use histograms of upper and lower bounds, as well as range
4003 lengths, for <link linkend="rangetypes">range types</link>
4004 (Alexander Korotkov)
4010 Improve optimizer's cost estimation for index access (Tom Lane)
4016 Improve optimizer's hash table size estimate for
4017 doing <literal>DISTINCT</> via hash aggregation (Tom Lane)
4023 Suppress no-op Result and Limit plan nodes
4024 (Kyotaro Horiguchi, Amit Kapila, Tom Lane)
4030 Reduce optimizer overhead by not keeping plans on the basis of cheap
4031 startup cost when the optimizer only cares about total cost overall
4041 <title>General Performance</title>
4047 Add <link linkend="SQL-COPY"><command>COPY FREEZE</></link>
4048 option to avoid the overhead of marking tuples as frozen later
4049 (Simon Riggs, Jeff Davis)
4055 Improve performance of <link
4056 linkend="datatype-numeric"><type>NUMERIC</></link> calculations
4063 Improve synchronization of sessions waiting for <link
4064 linkend="guc-commit-delay"><varname>commit_delay</></link>
4069 This greatly improves the usefulness of <varname>commit_delay</>.
4075 Improve performance of the <link
4076 linkend="SQL-CREATETABLE"><command>CREATE TEMPORARY TABLE ... ON
4077 COMMIT DELETE ROWS</></link> option by not truncating such temporary
4078 tables in transactions that haven't touched any temporary tables
4079 (Heikki Linnakangas)
4085 Make vacuum recheck visibility after it has removed expired tuples
4090 This increases the chance of a page being marked as all-visible.
4096 Add per-resource-owner lock caches (Jeff Janes)
4100 This speeds up lock bookkeeping at statement completion in
4101 multi-statement transactions that hold many locks; it is particularly
4102 useful for <application>pg_dump</>.
4108 Avoid scanning the entire relation cache at commit of a transaction
4109 that creates a new relation (Jeff Janes)
4113 This speeds up sessions that create many tables in successive
4114 small transactions, such as a <application>pg_restore</> run.
4120 Improve performance of transactions that drop many relations
4130 <title>Monitoring</title>
4136 Add optional ability to <link
4137 linkend="app-initdb-data-checksums">checksum</link> data pages and
4138 report corruption (Simon Riggs, Jeff Davis, Greg Smith, Ants Aasma)
4142 The checksum option can be set during <link
4143 linkend="APP-INITDB">initdb</link>.
4149 Split the <link linkend="monitoring-stats">statistics collector's</link>
4150 data file into separate global and per-database files (Tomas Vondra)
4154 This reduces the I/O required for statistics tracking.
4160 Fix the statistics collector to operate properly in cases where the
4161 system clock goes backwards (Tom Lane)
4165 Previously, statistics collection would stop until the time again
4166 reached the latest time previously recorded.
4172 Emit an informative message to postmaster standard error when we
4173 are about to stop logging there
4178 This should help reduce user confusion about where to look for log
4179 output in common configurations that log to standard error only during
4189 <title>Authentication</title>
4195 When an authentication failure occurs, log the relevant
4196 <link linkend="auth-pg-hba-conf"><filename>pg_hba.conf</></link>
4197 line, to ease debugging of unintended failures
4204 Improve <link linkend="auth-ldap"><acronym>LDAP</></link> error
4205 reporting and documentation (Peter Eisentraut)
4211 Add support for specifying <acronym>LDAP</> authentication parameters
4212 in <acronym>URL</> format, per RFC 4516 (Peter Eisentraut)
4219 linkend="guc-ssl-ciphers"><varname>ssl_ciphers</></link> parameter
4220 to start with <literal>DEFAULT</>, rather than <literal>ALL</>,
4221 then remove insecure ciphers (Magnus Hagander)
4225 This should yield a more appropriate SSL cipher set.
4231 Parse and load <link
4232 linkend="auth-username-maps"><filename>pg_ident.conf</></link>
4233 once, not during each connection (Amit Kapila)
4237 This is similar to how <filename>pg_hba.conf</> is processed.
4246 <title>Server Settings</title>
4252 Greatly reduce System V <link linkend="sysvipc">shared
4253 memory</link> requirements (Robert Haas)
4257 On Unix-like systems, <function>mmap()</> is now used for most
4258 of <productname>PostgreSQL</>'s shared memory. For most users, this
4259 will eliminate any need to adjust kernel parameters for shared memory.
4265 Allow the postmaster to listen on multiple Unix-domain sockets
4266 (Honza Horák)
4270 The configuration parameter
4271 <varname>unix_socket_directory</> is replaced by <link
4272 linkend="guc-unix-socket-directories"><varname>unix_socket_directories</></link>,
4273 which accepts a list of directories.
4279 Allow a directory of configuration files to be processed (Magnus
4280 Hagander, Greg Smith, Selena Deckelmann)
4284 Such a directory is specified with <link
4285 linkend="config-includes"><varname>include_dir</></link> in the server
4292 Increase the maximum <link
4293 linkend="APP-INITDB">initdb</link>-configured value for <link
4294 linkend="guc-shared-buffers"><varname>shared_buffers</></link>
4295 to 128MB (Robert Haas)
4299 This is the maximum value that initdb will attempt to set in <link
4300 linkend="config-setting-configuration-file"><filename>postgresql.conf</></link>;
4301 the previous maximum was 32MB.
4307 Remove the <link linkend="guc-external-pid-file">external
4308 <acronym>PID</> file</link>, if any, on postmaster exit
4320 <title>Replication and Recovery</title>
4326 Allow a streaming replication standby to <link
4327 linkend="protocol-replication">follow a timeline switch</link>
4328 (Heikki Linnakangas)
4332 This allows streaming standby servers to receive WAL data from a slave
4333 newly promoted to master status. Previously, other standbys would
4334 require a resync to begin following the new master.
4340 Add <acronym>SQL</> functions <link
4341 linkend="functions-admin-backup"><function>pg_is_in_backup()</></link>
4343 linkend="functions-admin-backup"><function>pg_backup_start_time()</></link>
4348 These functions report the status of base backups.
4354 Improve performance of streaming log shipping with <link
4355 linkend="guc-synchronous-commit"><varname>synchronous_commit</></link>
4356 disabled (Andres Freund)
4362 Allow much faster promotion of a streaming standby to primary (Simon
4363 Riggs, Kyotaro Horiguchi)
4369 Add the last checkpoint's redo location to <link
4370 linkend="APP-PGCONTROLDATA"><application>pg_controldata</></link>'s
4371 output (Fujii Masao)
4375 This information is useful for determining which <acronym>WAL</>
4376 files are needed for restore.
4382 Allow tools like <link
4383 linkend="app-pgreceivexlog"><application>pg_receivexlog</></link>
4384 to run on computers with different architectures (Heikki
4389 WAL files can still only be replayed on servers with the same
4390 architecture as the primary; but they can now be transmitted to and
4391 stored on machines of any architecture, since the
4392 streaming replication protocol is now machine-independent.
4399 linkend="app-pgbasebackup"><application>pg_basebackup</></link>
4400 <option>--write-recovery-conf</> output a
4401 minimal <filename>recovery.conf</> file (Zoltán
4402 Böszörményi, Magnus Hagander)
4406 This simplifies setting up a standby server.
4413 linkend="app-pgreceivexlog"><application>pg_receivexlog</></link>
4415 linkend="app-pgbasebackup"><application>pg_basebackup</></link>
4416 <option>--xlog-method</> to handle streaming timeline switches
4417 (Heikki Linnakangas)
4424 linkend="guc-wal-receiver-timeout"><varname>wal_receiver_timeout</></link>
4425 parameter to control the <acronym>WAL</> receiver's timeout
4430 This allows more rapid detection of connection failure.
4436 Change the <link linkend="wal"><acronym>WAL</></link> record format to
4437 allow splitting the record header across pages (Heikki Linnakangas)
4441 The new format is slightly more compact, and is more efficient to
4451 <title>Queries</title>
4457 Implement <acronym>SQL</>-standard <link
4458 linkend="queries-lateral"><literal>LATERAL</></link> option for
4459 <literal>FROM</>-clause subqueries and function calls (Tom Lane)
4463 This feature allows subqueries and functions in <literal>FROM</> to
4464 reference columns from other tables in the <literal>FROM</>
4465 clause. The <literal>LATERAL</> keyword is optional for functions.
4471 Add support for piping <link
4472 linkend="SQL-COPY"><command>COPY</></link> and <link
4473 linkend="APP-PSQL"><application>psql</></link> <command>\copy</>
4474 data to/from an external program (Etsuro Fujita)
4480 Allow a multirow <link
4481 linkend="SQL-VALUES"><literal>VALUES</></link> clause in a rule
4482 to reference <literal>OLD</>/<literal>NEW</> (Tom Lane)
4491 <title>Object Manipulation</title>
4497 Add support for <link linkend="event-triggers">event triggers</link>
4498 (Dimitri Fontaine, Robert Haas, Álvaro Herrera)
4502 This allows server-side functions written in event-enabled
4503 languages to be called when DDL commands are run.
4509 Allow <link linkend="SQL-CREATEFOREIGNDATAWRAPPER">foreign data
4510 wrappers</link> to support writes (inserts/updates/deletes) on foreign
4511 tables (KaiGai Kohei)
4517 Add <link linkend="SQL-CREATESCHEMA"><command>CREATE SCHEMA ... IF
4518 NOT EXISTS</></link> clause (Fabrízio de Royes Mello)
4524 Make <link linkend="SQL-REASSIGN-OWNED"><command>REASSIGN
4525 OWNED</></link> also change ownership of shared objects
4526 (Álvaro Herrera)
4532 Make <link linkend="sql-createaggregate"><command>CREATE
4533 AGGREGATE</></link> complain if the given initial value string is not
4534 valid input for the transition datatype (Tom Lane)
4540 Suppress <link linkend="SQL-CREATETABLE"><command>CREATE
4541 TABLE</></link>'s messages about implicit index and sequence creation
4546 These messages now appear at <literal>DEBUG1</> verbosity, so that
4547 they will not be shown by default.
4553 Allow <link linkend="SQL-DROPTABLE"><command>DROP TABLE IF
4554 EXISTS</></link> to succeed when a non-existent schema is specified
4555 in the table name (Bruce Momjian)
4559 Previously, it threw an error if the schema did not exist.
4565 Provide clients with <link
4566 linkend="libpq-pqresulterrorfield">constraint violation details</link>
4567 as separate fields (Pavel Stehule)
4571 This allows clients to retrieve table, column, data type, or
4572 constraint name error details. Previously such information had to be
4573 extracted from error strings. Client library support is required to
4574 access these fields.
4581 <title><command>ALTER</></title>
4587 Support <literal>IF NOT EXISTS</> option in <link
4588 linkend="SQL-ALTERTYPE"><command>ALTER TYPE ... ADD VALUE</></link>
4593 This is useful for conditionally adding values to enumerated types.
4599 Add <link linkend="SQL-ALTERROLE"><command>ALTER ROLE ALL
4600 SET</></link> to establish settings for all users (Peter Eisentraut)
4604 This allows settings to apply to all users in all databases. <link
4605 linkend="SQL-ALTERDATABASE"><command>ALTER DATABASE SET</></link>
4606 already allowed addition of settings for all users in a single
4607 database. <filename>postgresql.conf</> has a similar effect.
4613 Add support for <link linkend="SQL-ALTERRULE"><command>ALTER RULE
4614 ... RENAME</></link> (Ali Dar)
4623 <title><link linkend="rules-views"><command>VIEWs</></link></title>
4629 Add <link linkend="SQL-CREATEMATERIALIZEDVIEW">materialized
4630 views</link> (Kevin Grittner)
4634 Unlike ordinary views, where the base tables are read on every access,
4635 materialized views create physical tables at creation or refresh time.
4636 Access to the materialized view then reads from its physical
4637 table. There is not yet any facility for incrementally refreshing
4638 materialized views or auto-accessing them via base table access.
4644 Make simple views <link
4645 linkend="SQL-CREATEVIEW-updatable-views">auto-updatable</link>
4650 Simple views that reference some or all columns from a
4651 single base table are now updatable by default. More
4652 complex views can be made updatable using <link
4653 linkend="SQL-CREATETRIGGER"><literal>INSTEAD OF</></link> triggers
4654 or <link linkend="SQL-CREATERULE"><literal>INSTEAD</></link> rules.
4660 Add <link linkend="SQL-CREATEVIEW"><command>CREATE RECURSIVE
4661 VIEW</></link> syntax (Peter Eisentraut)
4665 Internally this is translated into <command>CREATE VIEW ... WITH
4672 Improve view/rule printing code to handle cases where referenced
4673 tables are renamed, or columns are renamed, added, or dropped
4678 Table and column renamings can produce cases where, if we merely
4679 substitute the new name into the original text of a rule or view, the
4680 result is ambiguous. This change fixes the rule-dumping code to insert
4681 manufactured table and column aliases when needed to preserve the
4693 <title>Data Types</title>
4699 Increase the maximum size of <link linkend="largeObjects">large
4700 objects</link> from 2GB to 4TB (Nozomi Anzai, Yugo Nagata)
4704 This change includes adding 64-bit-capable large object access
4705 functions, both in the server and in libpq.
4711 Allow text <link linkend="datatype-timezones">timezone
4712 designations</link>, e.g. <quote>America/Chicago</>, in the
4713 <quote>T</> field of <acronym>ISO</>-format <type>timestamptz</type>
4714 input (Bruce Momjian)
4721 <title><link linkend="datatype-json"><type>JSON</></link></title>
4727 Add <link linkend="functions-json">operators and functions</link>
4728 to extract elements from <type>JSON</> values (Andrew Dunstan)
4734 Allow <type>JSON</> values to be <link
4735 linkend="functions-json">converted into records</link>
4742 Add <link linkend="functions-json">functions</link> to convert
4743 scalars, records, and <type>hstore</> values to <type>JSON</> (Andrew
4756 <title>Functions</title>
4763 linkend="array-functions-table"><function>array_remove()</></link>

4766 functions (Marco Nenciarini, Gabriele Bartolini)
4773 linkend="functions-string-other"><function>concat()</></link>
4775 linkend="functions-string-format"><function>format()</></link>
4776 to properly expand <literal>VARIADIC</>-labeled arguments
4784 linkend="functions-string-format"><function>format()</></link>
4785 to provide field width and left/right alignment options (Pavel Stehule)
4792 linkend="functions-formatting-table"><function>to_char()</></link>,
4794 linkend="functions-formatting-table"><function>to_date()</></link>,
4796 linkend="functions-formatting-table"><function>to_timestamp()</></link>
4797 handle negative (BC) century values properly
4802 Previously the behavior was either wrong or inconsistent
4803 with positive/<acronym>AD</> handling, e.g. with the format mask
4804 <quote>IYYY-IW-DY</>.
4811 linkend="functions-formatting-table"><function>to_date()</></link>
4813 linkend="functions-formatting-table"><function>to_timestamp()</></link>
4814 return proper results when mixing <acronym>ISO</> and Gregorian
4815 week/day designations (Bruce Momjian)
4822 linkend="functions-info-catalog-table"><function>pg_get_viewdef()</></link>
4823 to start a new line by default after each <literal>SELECT</> target
4824 list entry and <literal>FROM</> entry (Marko Tiikkaja)
4828 This reduces line length in view printing, for instance in <link
4829 linkend="APP-PGDUMP"><application>pg_dump</></link> output.
4835 Fix <function>map_sql_value_to_xml_value()</> to print values of
4836 domain types the same way their base type would be printed
4841 There are special formatting rules for certain built-in types such as
4842 <type>boolean</>; these rules now also apply to domains over these
4852 <title>Server-Side Languages</title>
4855 <title><link linkend="plpgsql">PL/pgSQL</link> Server-Side Language</title>
4861 Allow PL/pgSQL to use <literal>RETURN</> with a composite-type
4862 expression (Asif Rehman)
4866 Previously, in a function returning a composite type,
4867 <literal>RETURN</> could only reference a variable of that type.
4873 Allow PL/pgSQL to access <link
4874 linkend="plpgsql-exception-diagnostics">constraint violation
4875 details</link> as separate fields (Pavel Stehule)
4881 Allow PL/pgSQL to access the number of rows processed by
4882 <link linkend="SQL-COPY"><command>COPY</></link> (Pavel Stehule)
4886 A <command>COPY</> executed in a PL/pgSQL function now updates the
4887 value retrieved by <link
4888 linkend="plpgsql-statements-diagnostics"><command>GET DIAGNOSTICS
4889 x = ROW_COUNT</></link>.
4895 Allow unreserved keywords to be used as identifiers everywhere in
4900 In certain places in the PL/pgSQL grammar, keywords had to be quoted
4901 to be used as identifiers, even if they were nominally unreserved.
4910 <title><link linkend="plpython">PL/Python</link> Server-Side Language</title>
4916 Add PL/Python result object string handler (Peter Eisentraut)
4920 This allows <literal>plpy.debug(rv)</literal> to output something reasonable.
4926 Make PL/Python convert OID values to a proper Python numeric type
4933 Handle <link linkend="spi"><acronym>SPI</></link> errors raised
4934 explicitly (with PL/Python's <literal>RAISE</>) the same as
4935 internal <acronym>SPI</> errors (Oskari Saarenmaa and Jan Urbanski)
4946 <title>Server Programming Interface (<link linkend="spi">SPI</link>)</title>
4952 Prevent leakage of <acronym>SPI</> tuple tables during subtransaction
4957 At the end of any failed subtransaction, the core SPI code now
4958 releases any SPI tuple tables that were created during that
4959 subtransaction. This avoids the need for SPI-using code to keep track
4960 of such tuple tables and release them manually in error-recovery code.
4961 Failure to do so caused a number of transaction-lifespan memory leakage
4962 issues in PL/pgSQL and perhaps other SPI clients. <link
4963 linkend="spi-spi-freetupletable"><function>SPI_freetuptable()</></link>
4964 now protects itself against multiple freeing requests, so any existing
4965 code that did take care to clean up shouldn't be broken by this change.
4971 Allow <acronym>SPI</> functions to access the number of rows processed
4972 by <link linkend="SQL-COPY"><command>COPY</></link> (Pavel Stehule)
4981 <title>Client Applications</title>
4987 Add command-line utility <link
4988 linkend="app-pg-isready"><application>pg_isready</></link> to
4989 check if the server is ready to accept connections (Phil Sorber)
4995 Support multiple <option>--table</> arguments for <link

4997 <link linkend="APP-CLUSTERDB"><application>clusterdb</></link>,
4998 <link linkend="APP-REINDEXDB"><application>reindexdb</></link>,
4999 and <link linkend="APP-VACUUMDB"><application>vacuumdb</></link>
5004 This is similar to the way <link
5005 linkend="APP-PGDUMP"><application>pg_dump</></link>'s
5006 <option>--table</> option works.
5012 Add <option>--dbname</> option to <link

5039 Adjust function cost settings so <application>psql</> tab
5040 completion and pattern searching are more efficient (Tom Lane)
5046 Improve <application>psql</>'s tab completion coverage (Jeff Janes,
5047 Dean Rasheed, Peter Eisentraut, Magnus Hagander)
5053 Allow the <application>psql</> <option>--single-transaction</>
5054 mode to work when reading from standard input (Fabien Coelho,
5059 Previously this option only worked when reading from a file.
5065 Remove <application>psql</> warning when connecting to an older
5066 server (Peter Eisentraut)
5070 A warning is still issued when connecting to a server of a newer major
5071 version than <application>psql</>'s.
5078 <title><link linkend="APP-PSQL-meta-commands">Backslash Commands</link></title>
5084 Add <application>psql</> command <command>\watch</> to repeatedly

5112 Allow <application>psql</> command <command>\l</> to accept a database
5113 name pattern (Peter Eisentraut)
5119 In <application>psql</>, do not allow <command>\connect</> to
5120 use defaults if there is no active connection (Bruce Momjian)
5124 This might be the case if the server had crashed.
5130 Properly reset state after failure of a SQL command executed with
5131 <application>psql</>'s <literal>\g</> <replaceable>file</>
5136 Previously, the output from subsequent SQL commands would unexpectedly
5137 continue to go to the same file.
5146 <title>Output</title>
5152 Add a <literal>latex-longtable</> output format to
5153 <application>psql</> (Bruce Momjian)
5157 This format allows tables to span multiple pages.
5163 Add a <literal>border=3</> output mode to the <application>psql</>

5247 Add initdb <option>--sync-only</> option to sync the data directory to durable
5248 storage (Bruce Momjian)
5252 This is used by <link

5285 Create a centralized timeout <acronym>API</> (Zoltán
5286 Böszörményi)
5292 Create libpgcommon and move <function>pg_malloc()</> and other

5297 This allows libpgport to be used solely for portability-related code.
5303 Add support for list links embedded in larger structs (Andres Freund)
5309 Use <literal>SA_RESTART</> for all signals,

5434 This is useful for event triggers.
5440 Invent pre-commit/pre-prepare/pre-subcommit events for transaction
