Changes
+
+
+
+
+ Fix multiple bugs in GiST index page split processing (Heikki
+ Linnakangas)
+
+
+ The probability of occurrence was low, but these could lead to index
+ corruption.
+
+
+
+
+ Avoid possibly accessing off the end of memory in ANALYZE
+ (Noah Misch)
+
+
+ This fixes a very-low-probability server crash scenario.
+
+
+
+
+ Fix race condition in relcache init file invalidation (Tom Lane)
+
+
+ There was a window wherein a new backend process could read a stale init
+ file but miss the inval messages that would tell it the data is stale.
+ The result would be bizarre failures in catalog accesses, typically
+ could not read block 0 in file ... later during startup.
+
+
+
+
+ Fix memory leak at end of a GiST index scan (Tom Lane)
+
+
+ Commands that perform many separate GiST index scans, such as
+ verification of a new GiST-based exclusion constraint on a table
+ already containing many rows, could transiently require large amounts of
+ memory due to this leak.
+
+
+
+
+ Fix performance problem when constructing a large, lossy bitmap
+ (Tom Lane)
+
+
+
+
+ Fix array- and path-creating functions to ensure padding bytes are
+ zeroes (Tom Lane)
+
+
+ This avoids some situations where the planner will think that
+ semantically-equal constants are not equal, resulting in poor
+ optimization.
+
+
+
+
+ Work around gcc 4.6.0 bug that breaks WAL replay (Tom Lane)
+
+
+ This could lead to loss of committed transactions after a server crash.
+
+
+
+
+ Fix dump bug for VALUES in a view (Tom Lane)
+
+
+
+
+ Disallow SELECT FOR UPDATE/SHARE on sequences (Tom Lane)
+
+
+ This operation doesn't work as expected and can lead to failures.
+
+
+
+
+ Defend against integer overflow when computing size of a hash table (Tom
+ Lane)
+
+
+
+
+ Fix portability bugs in use of credentials control messages for
+ peer authentication (Tom Lane)
+
+
+
+
+ Fix typo in pg_srand48 seed initialization (Andres Freund)
+
+
+ This led to failure to use all bits of the provided seed. This function
+ is not used on most platforms (only those without srandom),
+ and the potential security exposure from a less-random-than-expected
+ seed seems minimal in any case.
+
+
+
+
+ Avoid integer overflow when the sum of LIMIT and
+ OFFSET values exceeds 2^63 (Heikki Linnakangas)
+
+
+
+
+ Add overflow checks to int4 and int8 versions of
+ generate_series() (Robert Haas)
+
+
+
+
+ Fix trailing-zero removal in to_char() (Marti Raudsepp)
+
+
+ In a format with FM and no digit positions
+ after the decimal point, zeroes to the left of the decimal point could
+ be removed incorrectly.
+
+
+
+
+ Fix pg_size_pretty() to avoid overflow for inputs close to
+ 2^63 (Tom Lane)
+
+
+
+
+ Fix
psql's counting of script file line numbers during+ COPY from a different file (Tom Lane)
+
+
+
+
+ Fix
pg_restore's direct-to-database mode for+ standard_conforming_strings (Tom Lane)
+
+
+
pg_restore could emit incorrect commands when restoring+ directly to a database server from an archive file that had been made
+ with standard_conforming_strings set to on.
+
+
+
+
+ Fix write-past-buffer-end and memory leak in
libpq's+ LDAP service lookup code (Albe Laurenz)
+
+
+
+
+ In
libpq, avoid failures when using nonblocking I/O+ and an SSL connection (Martin Pihlak, Tom Lane)
+
+
+
+
+ Improve libpq's handling of failures during connection startup
+ (Tom Lane)
+
+
+ In particular, the response to a server report of fork()
+ failure during SSL connection startup is now saner.
+
+
+
+
+ Make
ecpglib write double values with 15 digits+ precision (Akira Kurosawa)
+
+
+
+
+ Apply upstream fix for blowfish signed-character bug (CVE-2011-2483)
+ (Tom Lane)
+
+
+ contrib/pg_crypto's blowfish encryption code could give
+ wrong results on platforms where char is signed (which is most),
+ leading to encrypted passwords being weaker than they should be.
+
+
+
+
+ Fix memory leak in contrib/seg (Heikki Linnakangas)
+
+
+
+
+ Fix pgstatindex() to give consistent results for empty
+ indexes (Tom Lane)
+
+
+
+
+ Allow building with perl 5.14 (Alex Hunsaker)
+
+
+
+
+ Update configure script's method for probing existence of system
+ functions (Tom Lane)
+
+
+ The version of autoconf we used in 8.3 and 8.2 could be fooled by
+ compilers that perform link-time optimization.
+
+
+
+
+ Fix assorted issues with build and install file paths containing spaces
+ (Tom Lane)
+
+
+
+
+ Update time zone data files to
tzdata release 2011i+ for DST law changes in Canada, Egypt, Russia, Samoa, and South Sudan.

+
+
+
+
+ Fix SSPI login when multiple roundtrips are required (Ahmed Shinwari,

+
+
+ The typical symptom of this problem was The function requested is

+
+
+

+
+
+ This fixes some very-low-probability server crash scenarios.
+
+
+
+
+ Prevent intermittent hang in interactions of startup process with

+
+
+ This affected recovery in non-hot-standby cases.

+
+
+
+ Fix race condition in relcache init file invalidation (Tom Lane)
+
+
+ There was a window wherein a new backend process could read a stale init

+
+
+
+ Fix EXPLAIN to handle gating Result nodes within

+
+
+ The usual symptom of this oversight was bogus varno errors.

+
+
+

+ not supported errors during SSPI login.
+
+
+
+
+ Throw an error if pg_hba.conf contains hostssl
+ but SSL is disabled (Tom Lane)
+
+
+ This was concluded to be more user-friendly than the previous behavior
+ of silently ignoring such lines.
+
+
+
+
+ Fix typo in pg_srand48 seed initialization (Andres Freund)
+
+
+ This led to failure to use all bits of the provided seed. This function

+
+ Fix pg_size_pretty() to avoid overflow for inputs close to
+ 2^63 (Tom Lane)
+
+
+
+
+ Weaken plpgsql's check for typmod matching in record values (Tom Lane)
+
+
+ An overly enthusiastic check could lead to discarding length modifiers
+ that should have been kept.
+
+
+
+
+ Correctly handle quotes in locale names during
initdb+ (Heikki Linnakangas)
+
+
+ The case can arise with some Windows locales, such as People's
+ Republic of China.
+
+
+
+
+ Fix
pg_upgrade to preserve toast tables' relfrozenxids+ during an upgrade from 8.3 (Bruce Momjian)
+
+
+ Failure to do this could lead to pg_clog files being
+ removed too soon after the upgrade.
+
+
+
+

+
+
+
pg_restore could emit incorrect commands when restoring+ directly to a database server from an archive file that had been made
+ with standard_conforming_strings set to on.
+
+
+
+
+ Be more user-friendly about unsupported cases for parallel

+
Changes
+
+
+
+
+ Fix catalog cache invalidation after a VACUUM FULL or
+ CLUSTER on a system catalog (Tom Lane)
+
+
+ In some cases the relocation of a system catalog row to another place
+ would not be recognized by concurrent server processes, allowing catalog
+ corruption to occur if they then tried to update that row. The
+ worst-case outcome could be as bad as complete loss of a table.
+
+
+
+
+ Fix incorrect order of operations during sinval reset processing,
+ and ensure that TOAST OIDs are preserved in system catalogs (Tom
+ Lane)
+
+
+ These mistakes could lead to transient failures after a VACUUM
+ FULL or CLUSTER on a system catalog.
+
+
+
+
+ Fix bugs in indexing of in-doubt HOT-updated tuples (Tom Lane)
+
+
+ These bugs could result in index corruption after reindexing a system
+ catalog. They are not believed to affect user indexes.
+
+
+
+
+ Fix multiple bugs in GiST index page split processing (Heikki
+ Linnakangas)
+
+
+ The probability of occurrence was low, but these could lead to index
+ corruption.
+
+
+
+
+ Fix possible buffer overrun in tsvector_concat()
+ (Tom Lane)
+
+
+ The function could underestimate the amount of memory needed for its
+ result, leading to server crashes.
+
+
+
+
+ Fix crash in xml_recv when processing a
+ standalone parameter (Tom Lane)
+
+
+
+
+ Make pg_options_to_table return NULL for an option with no
+ value (Tom Lane)
+
+
+ Previously such cases would result in a server crash.
+
+
+
+
+ Avoid possibly accessing off the end of memory in ANALYZE
+ and in SJIS-2004 encoding conversion (Noah Misch)
+
+
+ This fixes some very-low-probability server crash scenarios.
+
+
+
+
+ Protect pg_stat_reset_shared() against NULL input (Magnus
+ Hagander)
+
+
+
+
+ Fix possible failure when a recovery conflict deadlock is detected
+ within a sub-transaction (Tom Lane)
+
+
+
+
+ Avoid spurious conflicts while recycling btree index pages during hot
+ standby (Noah Misch, Simon Riggs)
+
+
+
+
+ Shut down WAL receiver if it's still running at end of recovery (Heikki
+ Linnakangas)
+
+
+ The postmaster formerly panicked in this situation, but it's actually a
+ legitimate case.
+
+
+
+
+ Fix race condition in relcache init file invalidation (Tom Lane)
+
+
+ There was a window wherein a new backend process could read a stale init
+ file but miss the inval messages that would tell it the data is stale.
+ The result would be bizarre failures in catalog accesses, typically
+ could not read block 0 in file ... later during startup.
+
+
+
+
+ Fix memory leak at end of a GiST index scan (Tom Lane)
+
+
+ Commands that perform many separate GiST index scans, such as
+ verification of a new GiST-based exclusion constraint on a table
+ already containing many rows, could transiently require large amounts of
+ memory due to this leak.

+ Fix memory leak when encoding conversion has to be done on incoming
+ command strings and LISTEN is active (Tom Lane)
+
+
+
+
+ Fix incorrect memory accounting (leading to possible memory bloat) in
+ tuplestores supporting holdable cursors and plpgsql's RETURN
+ NEXT command (Tom Lane)
+
+
+
+
+ Fix trigger WHEN conditions when both BEFORE and
+ AFTER triggers exist (Tom Lane)
+
+
+ Evaluation of WHEN conditions for AFTER ROW
+ UPDATE triggers could crash if there had been a BEFORE
+ ROW trigger fired for the same update.
+
+
+
+
+ Fix performance problem when constructing a large, lossy bitmap
+ (Tom Lane)
+
+
+
+
+ Fix join selectivity estimation for unique columns (Tom Lane)
+
+
+ This fixes an erroneous planner heuristic that could lead to poor
+ estimates of the result size of a join.
+
+
+
+
+ Fix nested PlaceHolderVar expressions that appear only in sub-select
+ target lists (Tom Lane)
+
+
+ This mistake could result in outputs of an outer join incorrectly
+ appearing as NULL.
+
+
+
+
+ Allow the planner to assume that empty parent tables really are empty
+ (Tom Lane)
+
+
+ Normally an empty table is assumed to have a certain minimum size for
+ planning purposes; but this heuristic seems to do more harm than good
+ for the parent table of an inheritance hierarchy, which often is
+ permanently empty.
+
+
+
+
+ Allow nested EXISTS queries to be optimized properly (Tom
+ Lane)
+
+
+
+
+ Fix array- and path-creating functions to ensure padding bytes are
+ zeroes (Tom Lane)
+
+
+ This avoids some situations where the planner will think that
+ semantically-equal constants are not equal, resulting in poor
+ optimization.
+
+
+
+
+ Fix EXPLAIN to handle gating Result nodes within
+ inner-indexscan subplans (Tom Lane)
+
+
+ The usual symptom of this oversight was bogus varno errors.
+
+
+
+
+ Fix btree preprocessing of indexedcol IS
+ NULL conditions (Dean Rasheed)
+
+
+ Such a condition is unsatisfiable if combined with any other type of
+ btree-indexable condition on the same index column. The case was
+ handled incorrectly in 9.0.0 and later, leading to query output where
+ there should be none.
+
+
+
+
+ Work around gcc 4.6.0 bug that breaks WAL replay (Tom Lane)
+
+
+ This could lead to loss of committed transactions after a server crash.
+
+
+
+
+ Fix dump bug for VALUES in a view (Tom Lane)
+
+
+
+
+ Disallow SELECT FOR UPDATE/SHARE on sequences (Tom Lane)
+
+
+ This operation doesn't work as expected and can lead to failures.
+
+
+
+
+ Fix VACUUM so that it always updates
+ pg_class.reltuples/relpages (Tom
+ Lane)
+
+
+ This fixes some scenarios where autovacuum could make increasingly poor
+ decisions about when to vacuum tables.
+
+
+
+
+ Defend against integer overflow when computing size of a hash table (Tom
+ Lane)
+
+
+
+
+ Fix cases where CLUSTER might attempt to access
+ already-removed TOAST data (Tom Lane)
+
+
+
+
+ Fix premature timeout failures during initial authentication transaction
+ (Tom Lane)
+
+
+
+
+ Fix portability bugs in use of credentials control messages for
+ peer authentication (Tom Lane)
+
+
+
+
+ Fix SSPI login when multiple roundtrips are required (Ahmed Shinwari,
+ Magnus Hagander)
+
+
+ The typical symptom of this problem was The function requested is
+ not supported errors during SSPI login.
+
+
+
+
+ Fix failure when adding a new variable of a custom variable class to
+ postgresql.conf (Tom Lane)
+
+
+
+
+ Throw an error if pg_hba.conf contains hostssl
+ but SSL is disabled (Tom Lane)
+
+
+ This was concluded to be more user-friendly than the previous behavior
+ of silently ignoring such lines.
+
+
+
+
+ Fix failure when DROP OWNED BY attempts to remove default
+ privileges on sequences (Shigeru Hanada)
+
+
+
+
+ Fix typo in pg_srand48 seed initialization (Andres Freund)
+
+
+ This led to failure to use all bits of the provided seed. This function
+ is not used on most platforms (only those without srandom),
+ and the potential security exposure from a less-random-than-expected
+ seed seems minimal in any case.
+
+
+
+
+ Avoid integer overflow when the sum of LIMIT and
+ OFFSET values exceeds 2^63 (Heikki Linnakangas)
+
+
+
+
+ Add overflow checks to int4 and int8 versions of
+ generate_series() (Robert Haas)
+
+
+
+
+ Fix trailing-zero removal in to_char() (Marti Raudsepp)
+
+
+ In a format with FM and no digit positions
+ after the decimal point, zeroes to the left of the decimal point could
+ be removed incorrectly.
+
+
+
+
+ Fix pg_size_pretty() to avoid overflow for inputs close to
+ 2^63 (Tom Lane)
+
+
+
+
+ Weaken plpgsql's check for typmod matching in record values (Tom Lane)
+
+
+ An overly enthusiastic check could lead to discarding length modifiers
+ that should have been kept.
+
+
+
+
+ Correctly handle quotes in locale names during
initdb+ (Heikki Linnakangas)
+
+
+ The case can arise with some Windows locales, such as People's
+ Republic of China.
+
+
+
+
+ In
pg_upgrade, avoid dumping orphaned temporary tables+ (Bruce Momjian)
+
+
+ This prevents situations wherein table OID assignments could get out of
+ sync between old and new installations.
+
+
+
+
+ Fix
pg_upgrade to preserve toast tables' relfrozenxids+ during an upgrade from 8.3 (Bruce Momjian)
+
+
+ Failure to do this could lead to pg_clog files being
+ removed too soon after the upgrade.
+
+
+
+
+ In
pg_upgrade, fix the -l (log) option to+ work on Windows (Bruce Momjian)
+
+
+
+
+ In
pg_ctl, support silent mode for service registrations+ on Windows (MauMau)
+
+
+
+
+ Fix
psql's counting of script file line numbers during+ COPY from a different file (Tom Lane)
+
+
+
+
+ Fix
pg_restore's direct-to-database mode for+ standard_conforming_strings (Tom Lane)
+
+
+
pg_restore could emit incorrect commands when restoring+ directly to a database server from an archive file that had been made
+ with standard_conforming_strings set to on.
+
+
+
+
+ Be more user-friendly about unsupported cases for parallel
+
+
+ This change ensures that such cases are detected and reported before
+ any restore actions have been taken.
+
+
+
+
+ Fix write-past-buffer-end and memory leak in
libpq's+ LDAP service lookup code (Albe Laurenz)
+
+
+
+
+ In
libpq, avoid failures when using nonblocking I/O+ and an SSL connection (Martin Pihlak, Tom Lane)
+
+
+
+
+ Improve libpq's handling of failures during connection startup
+ (Tom Lane)
+
+
+ In particular, the response to a server report of fork()
+ failure during SSL connection startup is now saner.
+
+
+
+
+ Improve
libpq's error reporting for SSL failures (Tom+ Lane)
+
+
+
+
+ Fix PQsetvalue() to avoid possible crash when adding a new
+ tuple to a PGresult originally obtained from a server
+ query (Andrew Chernow)
+
+
+
+
+ Make
ecpglib write double values with 15 digits+ precision (Akira Kurosawa)
+
+
+
+
+ In
ecpglib, be sure LC_NUMERIC setting is+ restored after an error (Michael Meskes)
+
+
+
+
+ Apply upstream fix for blowfish signed-character bug (CVE-2011-2483)
+ (Tom Lane)
+
+
+ contrib/pg_crypto's blowfish encryption code could give
+ wrong results on platforms where char is signed (which is most),
+ leading to encrypted passwords being weaker than they should be.
+
+
+
+
+ Fix memory leak in contrib/seg (Heikki Linnakangas)
+
+
+
+
+ Fix pgstatindex() to give consistent results for empty
+ indexes (Tom Lane)
+
+
+
+
+ Allow building with perl 5.14 (Alex Hunsaker)
+
+
+
+
+ Fix assorted issues with build and install file paths containing spaces
+ (Tom Lane)
+
+
+
+
+ Update time zone data files to
tzdata release 2011i+ for DST law changes in Canada, Egypt, Russia, Samoa, and South Sudan.

Release 9.0.4
+
+
Release 9.1.1
+
+
+
Release Date
+ 2011-09-26
+
+
+ This release contains a small number of fixes from 9.1.0.
+ For information about new features in the 9.1 major release, see
+ .
+
+
+
+
Migration to Version 9.1.1
+
+ A dump/restore is not required for those running 9.1.X.
+
+
+
+
+
+
Changes
+
+
+
+
+ Make pg_options_to_table return NULL for an option with no
+ value (Tom Lane)
+
+
+ Previously such cases would result in a server crash.
+
+
+
+
+ Fix memory leak at end of a GiST index scan (Tom Lane)
+
+
+ Commands that perform many separate GiST index scans, such as
+ verification of a new GiST-based exclusion constraint on a table
+ already containing many rows, could transiently require large amounts of
+ memory due to this leak.
+
+
+
+
+ Fix explicit reference to pg_temp schema in CREATE
+ TEMPORARY TABLE (Robert Haas)
+
+
+ This used to be allowed, but failed in 9.1.0.
+
+
+
+
+
+
+
+
Release 9.1
rather than by manually invoking their SQL scripts
(Dimitri Fontaine, Tom Lane)
+
+ To update an existing database containing the 9.0 version of a contrib
+ module, use CREATE EXTENSION ... FROM unpackaged
+ to wrap the existing contrib module's objects into an extension. When
+ updating from a pre-9.0 version, drop the contrib module's objects
+ using its old uninstall script, then use CREATE EXTENSION.
