+
+
+ 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.
+
+
+
+
+
+ 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.
+
+
+
+
+
+ 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.
+
+
+
+
+
+ Fix log_line_prefix's %i escape,
+ which could produce junk early in backend startup (Tom Lane)
+
+
+
+
+
+ Prevent misinterpretation of partially-specified relation options
+ for TOAST tables (Itagaki Takahiro)
+
+
+
+ In particular, fillfactor would be read as zero if any
+ other reloption had been set for the table, leading to serious bloat.
+
+
+
+
+
+ Fix inheritance count tracking in ALTER TABLE ... ADD
+ CONSTRAINT (Robert Haas)
+
+
+
+
+
+ Fix possible data corruption in ALTER TABLE ... SET
+ TABLESPACE when archiving is enabled (Jeff Davis)
+
+
+
+
+
+ Allow CREATE DATABASE and ALTER DATABASE ... SET
+ TABLESPACE to be interrupted by query-cancel (Guillaume Lelarge)
+
+
+
+
+
+ Improve CREATE INDEX's checking of whether proposed index
+ expressions are immutable (Tom Lane)
+
+
+
+
+
+ Fix REASSIGN OWNED to handle operator classes and families
+ (Asko Tiidumaa)
+
+
+
+
+
+ Fix possible core dump when comparing two empty tsquery values
+ (Tom Lane)
+
+
+
+
+
+ Fix LIKE's handling of patterns containing %
+ followed by _ (Tom Lane)
+
+
+
+ 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)
+
+
+
+
+
+ In PL/Python, defend against null pointer results from
+ PyCObject_AsVoidPtr and PyCObject_FromVoidPtr
+ (Peter Eisentraut)
+
+
+
+
+
+ In libpq, fix full SSL certificate verification for the
+ case where both host and hostaddr are specified
+ (Tom Lane)
+
+
+
+
+
+ Make psql recognize DISCARD ALL as a command that should
+ not be encased in a transaction block in autocommit-off mode
+ (Itagaki Takahiro)
+
+
+
+
+
+ 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
+ (-L option) (Tom Lane)
+
+
+
+ The original code tended to fail if the -L file commanded
+ a non-default restore ordering.
+
+
+
+
+
+ Fix ecpg to process data from RETURNING
+ clauses correctly (Michael Meskes)
+
+
+
+
+
+ Fix some memory leaks in ecpg (Zoltan Boszormenyi)
+
+
+
+
+
+ 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)
+
+
+
+
+
+ Fix contrib/dblink to handle connection names longer than
+ 62 bytes correctly (Itagaki Takahiro)
+
+
+
+
+
+ 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 tzdata release 2010l
+ for DST law changes in Egypt and Palestine; also historical corrections
+ 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.
