+
+ Release 8.1.23
+
+
+ Release date
+ 2010-12-16
+
+
+
+ This release contains a variety of fixes from 8.1.22.
+ For information about new features in the 8.1 major release, see
+ .
+
+
+
+ This is expected to be the last PostgreSQL release
+ in the 8.1.X series. Users are encouraged to update to a newer
+ release branch soon.
+
+
+
+ Migration to Version 8.1.23
+
+
+ A dump/restore is not required for those running 8.1.X.
+ However, if you are upgrading from a version earlier than 8.1.18,
+ see the release notes for 8.1.18.
+
+
+
+
+
+ Changes
+
+
+
+
+
+ Force the default
+ wal_sync_method
+ to be fdatasync on Linux (Tom Lane, Marti Raudsepp)
+
+
+
+ The default on Linux has actually been fdatasync for many
+ years, but recent kernel changes caused PostgreSQL to
+ choose open_datasync instead. This choice did not result
+ in any performance improvement, and caused outright failures on
+ certain filesystems, notably ext4 with the
+ data=journal mount option.
+
+
+
+
+
+ Fix recovery from base backup when the starting checkpoint WAL record
+ is not in the same WAL segment as its redo point (Jeff Davis)
+
+
+
+
+
+ Add support for detecting register-stack overrun on IA64
+ (Tom Lane)
+
+
+
+ The IA64 architecture has two hardware stacks. Full
+ prevention of stack-overrun failures requires checking both.
+
+
+
+
+
+ Add a check for stack overflow in copyObject() (Tom Lane)
+
+
+
+ Certain code paths could crash due to stack overflow given a
+ sufficiently complex query.
+
+
+
+
+
+ Fix detection of page splits in temporary GiST indexes (Heikki
+ Linnakangas)
+
+
+
+ It is possible to have a concurrent page split in a
+ temporary index, if for example there is an open cursor scanning the
+ index when an insertion is done. GiST failed to detect this case and
+ hence could deliver wrong results when execution of the cursor
+ continued.
+
+
+
+
+
+ Avoid memory leakage while ANALYZE'ing complex index
+ expressions (Tom Lane)
+
+
+
+
+
+ Ensure an index that uses a whole-row Var still depends on its table
+ (Tom Lane)
+
+
+
+ An index declared like create index i on t (foo(t.*))
+ would not automatically get dropped when its table was dropped.
+
+
+
+
+
+ Do not inline a SQL function with multiple OUT
+ parameters (Tom Lane)
+
+
+
+ This avoids a possible crash due to loss of information about the
+ expected result rowtype.
+
+
+
+
+
+ Fix constant-folding of COALESCE() expressions (Tom Lane)
+
+
+
+ The planner would sometimes attempt to evaluate sub-expressions that
+ in fact could never be reached, possibly leading to unexpected errors.
+
+
+
+
+
+ Add print functionality for InhRelation nodes (Tom Lane)
+
+
+
+ This avoids a failure when debug_print_parse is enabled
+ and certain types of query are executed.
+
+
+
+
+
+ Fix incorrect calculation of distance from a point to a horizontal
+ line segment (Tom Lane)
+
+
+
+ This bug affected several different geometric distance-measurement
+ operators.
+
+
+
+
+
+ Fix PL/pgSQL's handling of simple
+ expressions to not fail in recursion or error-recovery cases (Tom Lane)
+
+
+
+
+
+ Fix bug in contrib/cube's GiST picksplit algorithm
+ (Alexander Korotkov)
+
+
+
+ This could result in considerable inefficiency, though not actually
+ incorrect answers, in a GiST index on a cube column.
+ If you have such an index, consider REINDEXing it after
+ installing this update.
+
+
+
+
+
+ Don't emit identifier will be truncated notices in
+ contrib/dblink except when creating new connections
+ (Itagaki Takahiro)
+
+
+
+
+
+ Fix potential coredump on missing public key in
+ contrib/pgcrypto (Marti Raudsepp)
+
+
+
+
+
+ Fix memory leak in contrib/xml2's XPath query functions
+ (Tom Lane)
+
+
+
+
+
+ Update time zone data files to tzdata release 2010o
+ for DST law changes in Fiji and Samoa;
+ also historical corrections for Hong Kong.
+
+
+
