Release 8.3.21
+
+
+
Release Date
+ 2012-09-24
+
+
+ This release contains a variety of fixes from 8.3.20.
+ For information about new features in the 8.3 major release, see
+ .
+
+
+ The
PostgreSQL community will stop releasing updates+ for the 8.3.X release series in February 2013.
+ Users are encouraged to update to a newer release branch soon.
+
+
+
+
Migration to Version 8.3.21
+
+ A dump/restore is not required for those running 8.3.X.
+
+
+ However, if you are upgrading from a version earlier than 8.3.17,
+ see the release notes for 8.3.17.
+
+
+
+
+
+
Changes
+
+
+
+
+ Improve page-splitting decisions in GiST indexes (Alexander Korotkov,
+ Robert Haas, Tom Lane)
+
+
+ Multi-column GiST indexes might suffer unexpected bloat due to this
+ error.
+
+
+
+
+ Fix cascading privilege revoke to stop if privileges are still held
+ (Tom Lane)
+
+
+ If we revoke a grant option from some role X, but
+ X still holds that option via a grant from someone
+ else, we should not recursively revoke the corresponding privilege
+ from role(s) Y that X had granted it
+ to.
+
+
+
+
+ Fix handling of SIGFPE when PL/Perl is in use (Andres Freund)
+
+
+ Perl resets the process's SIGFPE handler to
+ SIG_IGN, which could result in crashes later on. Restore
+ the normal Postgres signal handler after initializing PL/Perl.
+
+
+
+
+ Prevent PL/Perl from crashing if a recursive PL/Perl function is
+ redefined while being executed (Tom Lane)
+
+
+
+
+ Work around possible misoptimization in PL/Perl (Tom Lane)
+
+
+ Some Linux distributions contain an incorrect version of
+ pthread.h that results in incorrect compiled code in
+ PL/Perl, leading to crashes if a PL/Perl function calls another one
+ that throws an error.
+
+
+
+
+ Update time zone data files to
tzdata release 2012f+ for DST law changes in Fiji
+
+
+

+
+
+
+
Migration to Version 9.1.6
+
+ A dump/restore is not required for those running 9.1.X.
+
+
+ However, you may need to perform REINDEX operations to
+ recover from the effects of the data corruption bug described in the
+ first changelog item below.

+ Also, if you are upgrading from a version earlier than 9.1.4,

+
+
Changes
+
+
+
+
+ Fix persistence marking of shared buffers during WAL replay
+ (Jeff Davis)
+
+
+ This mistake can result in buffers not being written out during
+ checkpoints, resulting in data corruption if the server later crashes
+ without ever having written those buffers. Corruption can occur on
+ any server following crash recovery, but it is significantly more
+ likely to occur on standby slave servers since those perform much
+ more WAL replay. There is a low probability of corruption of btree
+ and GIN indexes. There is a much higher probability of corruption of
+ table visibility maps. Fortunately, visibility maps are
+ non-critical data in 9.1, so the worst consequence of such corruption
+ in 9.1 installations is transient inefficiency of vacuuming. Table
+ data proper cannot be corrupted by this bug.
+
+
+ While no index corruption due to this bug is known to have occurred
+ in the field, as a precautionary measure it is recommended that
+ production installations REINDEX all btree and GIN
+ indexes at a convenient time after upgrading to 9.1.6.
+
+
+ Also, if you intend to do an in-place upgrade to 9.2.X, before doing
+ so it is recommended to perform a VACUUM of all tables
+ while having
+ linkend="guc-vacuum-freeze-table-age">vacuum_freeze_table_age
+ set to zero. This will ensure that any lingering wrong data in the
+ visibility maps is corrected before 9.2.X can depend on it.
+ linkend="guc-vacuum-cost-delay">vacuum_cost_delay
+ can be adjusted to reduce the performance impact of vacuuming, while
+ causing it to take longer to finish.
+
+
+
+
+ Fix planner's assignment of executor parameters, and fix executor's
+ rescan logic for CTE plan nodes (Tom Lane)
+
+
+ These errors could result in wrong answers from queries that scan the
+ same WITH subquery multiple times.
+
+
+
+
+ Fix misbehavior when
+ linkend="guc-default-transaction-isolation">default_transaction_isolation
+ is set to serializable (Kevin Grittner, Tom Lane, Heikki
+ Linnakangas)
+
+
+ Symptoms include crashes at process start on Windows, and crashes in
+ hot standby operation.
+
+
+
+
+ Improve selectivity estimation for text search queries involving
+ prefixes, i.e. word:* patterns (Tom Lane)
+
+
+
+
+
+
+ Improve page-splitting decisions in GiST indexes (Alexander Korotkov,
+ Robert Haas, Tom Lane)
+
+
+ Multi-column GiST indexes might suffer unexpected bloat due to this
+ error.
+
+
+
+
+ Fix cascading privilege revoke to stop if privileges are still held
+ (Tom Lane)
+
+
+ If we revoke a grant option from some role X, but
+ X still holds that option via a grant from someone
+ else, we should not recursively revoke the corresponding privilege
+ from role(s) Y that X had granted it
+ to.
+
+
+
+
+ Disallow extensions from containing the schema they are assigned to
+ (Thom Brown)
+
+
+ This situation creates circular dependencies that confuse
+
pg_dump and probably other things. It's confusing+ for humans too, so disallow it.
+
+
+
+
+ Improve error messages for Hot Standby misconfiguration errors
+ (Gurjeet Singh)
+
+
+
+
+ Make
configure probe for mbstowcs_l (Tom+ Lane)
+
+
+ This fixes build failures on some versions of AIX.
+
+
+
+
+ Fix handling of SIGFPE when PL/Perl is in use (Andres Freund)
+
+
+ Perl resets the process's SIGFPE handler to
+ SIG_IGN, which could result in crashes later on. Restore
+ the normal Postgres signal handler after initializing PL/Perl.
+
+
+
+
+ Prevent PL/Perl from crashing if a recursive PL/Perl function is
+ redefined while being executed (Tom Lane)
+
+
+
+
+ Work around possible misoptimization in PL/Perl (Tom Lane)
+
+
+ Some Linux distributions contain an incorrect version of
+ pthread.h that results in incorrect compiled code in
+ PL/Perl, leading to crashes if a PL/Perl function calls another one
+ that throws an error.
+
+
+
+
+ Fix bugs in contrib/pg_trgm's LIKE pattern
+ analysis code (Fujii Masao)
+
+
+ LIKE queries using a trigram index could produce wrong
+ results if the pattern contained LIKE escape characters.
+
+
+
+
+ Fix
pg_upgrade's handling of line endings on Windows+ (Andrew Dunstan)
+
+
+ Previously,
pg_upgrade might add or remove carriage+ returns in places such as function bodies.
+
+
+
+
+ On Windows, make
pg_upgrade use backslash path+ separators in the scripts it emits (Andrew Dunstan)
