Release date
+ 2010-10-04
+
+
+ This release contains a variety of fixes from 7.4.29.
+ For information about new features in the 7.4 major release, see
+ .
+
+
+ This is expected to be the last
PostgreSQL release+ in the 7.4.X series. Users are encouraged to update to a newer
+ release branch soon.
+
+
+
+
Migration to Version 7.4.30

Changes
+
+
+
+
+ Prevent possible crashes in pg_get_expr() by disallowing
+ it from being called with an argument that is not one of the system
+ catalog columns it's intended to be used with
+ (Heikki Linnakangas, Tom Lane)
+
+
+
+
+ Fix cannot handle unplanned sub-select
error (Tom Lane)
+
+
+ This occurred when a sub-select contains a join alias reference that
+ expands into an expression containing another sub-select.
+
+
+
+
+ Take care to fsync the contents of lockfiles (both
+ postmaster.pid and the socket lockfile) while writing them
+ (Tom Lane)
+
+
+ This omission could result in corrupted lockfile contents if the
+ machine crashes shortly after postmaster start. That could in turn
+ prevent subsequent attempts to start the postmaster from succeeding,
+ until the lockfile is manually removed.
+
+
+
+
+ Improve contrib/dblink's handling of tables containing
+ dropped columns (Tom Lane)
+
+
+
+
+ Fix connection leak after duplicate connection name
+ errors in contrib/dblink (Itagaki Takahiro)
+
+
+
+
+ Update build infrastructure and documentation to reflect the source code
+ repository's move from CVS to Git (Magnus Hagander and others)

+
+

+
+
+ Prevent possible crashes in pg_get_expr() by disallowing

+ catalog columns it's intended to be used with
+ (Heikki Linnakangas, Tom Lane)
+
+
+
+
+ Fix Windows shared-memory allocation code
+ (Tsutomu Yamada, Magnus Hagander)
+
+
+ This bug led to the often-reported could not reattach to shared
+ memory error message. This is a back-patch of a fix that was
+ applied to newer branches some time ago.
+
+
+
+
+ Treat exit code 128 (ERROR_WAIT_NO_CHILDREN) as non-fatal on
+ Windows (Magnus Hagander)
+
+
+ Under high load, Windows processes will sometimes fail at startup with
+ this error code. Formerly the postmaster treated this as a panic
+ condition and restarted the whole database, but that seems to be
+ an overreaction.
+
+
+
+
+ Fix possible duplicate scans of UNION ALL member relations
+ (Tom Lane)
+
+
+
+
+ Fix cannot handle unplanned sub-select
error (Tom Lane)
+
+
+ This occurred when a sub-select contains a join alias reference that

+
+
+
+
+ Reduce PANIC to ERROR in some occasionally-reported btree failure cases,
+ and provide additional detail in the resulting error messages
+ (Tom Lane)
+
+
+ This should improve the system's robustness with corrupted indexes.

+
+
+
+
+ Add hstore(text, text)
+ function to contrib/hstore (Robert Haas)
+
+
+ This function is the recommended substitute for the now-deprecated
+ => operator. It was back-patched so that future-proofed

+
+
+
+
+ Fix incorrect usage of non-strict OR joinclauses in Append indexscans
+ (Tom Lane)
+
+
+ This is a back-patch of an 8.4 fix that was missed in the 8.3 branch.
+ This corrects an error introduced in 8.3.8 that could cause incorrect
+ results for outer joins when the inner relation is an inheritance tree
+ or UNION ALL subquery.
+
+
+
+
+ Fix possible duplicate scans of UNION ALL member relations
+ (Tom Lane)
+
+
+
+
+ Fix cannot handle unplanned sub-select
error (Tom Lane)
+
+
+ This occurred when a sub-select contains a join alias reference that
+ expands into an expression containing another sub-select.
+
+
+
+
+ Fix failure to mark cached plans as transient (Tom Lane)
+
+
+ If a plan is prepared while CREATE INDEX CONCURRENTLY is
+ in progress for one of the referenced tables, it is supposed to be
+ re-planned once the index is ready for use. This was not happening
+ reliably.
+
+

+ (Tao Ma, Tom Lane)
+
+
+
+
+ Improve merge join's handling of NULLs in the join columns (Tom Lane)
+
+
+ A merge join can now stop entirely upon reaching the first NULL,
+ if the sort order is such that NULLs sort high.
+
+
+
+
+ Take care to fsync the contents of lockfiles (both
+ postmaster.pid and the socket lockfile) while writing them
+ (Tom Lane)
+
+

+
+
+
+
+ Avoid holding open old WAL segments in the walwriter process
+ (Magnus Hagander, Heikki Linnakangas)
+

+
+ Fix log_line_prefix's %i escape,

+
+
+

+ (Tom Lane)

Changes
+
+
+
+
+ Prevent possible crashes in pg_get_expr() by disallowing
+ it from being called with an argument that is not one of the system
+ catalog columns it's intended to be used with
+ (Heikki Linnakangas, Tom Lane)
+
+
+

+ this error code. Formerly the postmaster treated this as a panic
+ condition and restarted the whole database, but that seems to be
+ an overreaction.
+
+
+
+
+ Fix incorrect placement of placeholder evaluation (Tom Lane)
+
+
+ This bug could result in query outputs being non-null when they
+ should be null, in cases where the inner side of an outer join
+ is a sub-select with non-strict expressions in its output list.
+
+
+
+
+ Fix possible duplicate scans of UNION ALL member relations
+ (Tom Lane)
+
+
+
+
+ Fix cannot handle unplanned sub-select
error (Tom Lane)
+
+
+ This occurred when a sub-select contains a join alias reference that
+ expands into an expression containing another sub-select.
+
+
+
+
+ Fix mishandling of whole-row Vars that reference a view or sub-select
+ and appear within a nested sub-select (Tom Lane)
+
+
+
+
+ Fix mishandling of cross-type IN comparisons (Tom Lane)
+
+
+ This could result in failures if the planner tried to implement an
+ IN join with a sort-then-unique-then-plain-join plan.
+
+
+
+
+ Fix computation of ANALYZE statistics for tsvector
+ columns (Jan Urbanski)
+
+
+ The original coding could produce incorrect statistics, leading to
+ poor plan choices later.
+
+
+
+
+ Improve planner's estimate of memory used by array_agg(),
+ string_agg(), and similar aggregate functions
+ (Hitoshi Harada)
+
+
+ The previous drastic underestimate could lead to out-of-memory failures
+ due to inappropriate choice of a hash-aggregation plan.
+
+
+
+
+ Fix failure to mark cached plans as transient (Tom Lane)
+
+
+ If a plan is prepared while CREATE INDEX CONCURRENTLY is
+ in progress for one of the referenced tables, it is supposed to be
+ re-planned once the index is ready for use. This was not happening
+ reliably.
+
+
+

+ and provide additional detail in the resulting error messages
+ (Tom Lane)
+
+
+ This should improve the system's robustness with corrupted indexes.
+
+
+
+
+ Fix incorrect search logic for partial-match queries with GIN indexes
+ (Tom Lane)
+
+
+ Cases involving AND/OR combination of several GIN index conditions
+ didn't always give the right answer, and were sometimes much slower
+ than necessary.
+
+
+
+
+ Prevent show_session_authorization() from crashing within autovacuum
+ processes (Tom Lane)
+
+
+
+
+ Defend against functions returning setof record where not all the
+ returned rows are actually of the same rowtype (Tom Lane)
+
+
+
+
+ Fix possible corruption of pending trigger event lists during
+ subtransaction rollback (Tom Lane)
+
+
+ This could lead to a crash or incorrect firing of triggers.
+
+
+
+
+ Fix possible failure when hashing a pass-by-reference function result
+ (Tao Ma, Tom Lane)
+
+
+
+
+ Improve merge join's handling of NULLs in the join columns (Tom Lane)
+
+
+ A merge join can now stop entirely upon reaching the first NULL,
+ if the sort order is such that NULLs sort high.
+
+
+
+
+ Take care to fsync the contents of lockfiles (both
+ postmaster.pid and the socket lockfile) while writing them
+ (Tom Lane)
+
+
+ This omission could result in corrupted lockfile contents if the
+ machine crashes shortly after postmaster start. That could in turn
+ prevent subsequent attempts to start the postmaster from succeeding,
+ until the lockfile is manually removed.
+
+
+
+
+ Avoid recursion while assigning XIDs to heavily-nested
+ subtransactions (Andres Freund, Robert Haas)
+
+
+ The original coding could result in a crash if there was limited
+ stack space.
+
+
+
+
+ Avoid holding open old WAL segments in the walwriter process
+ (Magnus Hagander, Heikki Linnakangas)
+
+
+ The previous coding would prevent removal of no-longer-needed segments.

+ Prevent misinterpretation of partially-specified relation options
+ for TOAST tables (Itagaki Takahiro)

+
+
+ We've fixed this before, but there were still some incorrectly-handled
+ cases.
+
+
+
+
+ Re-allow input of Julian dates prior to 0001-01-01 AD (Tom Lane)
+
+
+ Input such as 'J100000'::date worked before 8.4,
+ but was unintentionally broken by added error-checking.
+

+ Fix PL/pgSQL to throw an error, not crash, if a cursor is closed within
+ a FOR loop that is iterating over that cursor
+ (Heikki Linnakangas)

+
+ Fix some issues in
pg_dump's handling of SQL/MED objects+ (Tom Lane)
+
+
+ Notably,
pg_dump would always fail if run by a+ non-superuser, which was not intended.
+
+
+
+
+ Improve
pg_dump and pg_restore's+ handling of non-seekable archive files (Tom Lane, Robert Haas)
+
+
+ This is important for proper functioning of parallel restore.
+
+
+
+
+ Improve parallel pg_restore's ability to cope with selective restore

+
+
+
+
+ Add hstore(text, text)
+ function to contrib/hstore (Robert Haas)
+
+
+ This function is the recommended substitute for the now-deprecated
+ => operator. It was back-patched so that future-proofed
+ code can be used with older server versions. Note that the patch will
+ be effective only after contrib/hstore is installed or
+ reinstalled in a particular database. Users might prefer to execute
+ the CREATE FUNCTION command by hand, instead.
+

+ Update build infrastructure and documentation to reflect the source code
+ repository's move from CVS to Git (Magnus Hagander and others)
+
+
+
+
+ Update time zone data files to

+ for Finland.
+
+
+ This change also adds new names for two Micronesian timezones:
+ Pacific/Chuuk is now preferred over Pacific/Truk (and the preferred
+ abbreviation is CHUT not TRUT) and Pacific/Pohnpei is preferred over
+ Pacific/Ponape.
+
+
+
+
+ Make Windows' N. Central Asia Standard Time timezone map to
+ Asia/Novosibirsk, not Asia/Almaty (Magnus Hagander)
+
+
+ Microsoft changed the DST behavior of this zone in the timezone update
+ from KB976098. Asia/Novosibirsk is a better match to its new behavior.
