+ Release 8.2.21
+
+
+ Release Date
+ 2011-04-18

+
+ This release contains a variety of fixes from 8.2.20.

+
+
+
+ Migration to Version 8.2.21
+
+

+
+
+ Avoid potential deadlock during catalog cache initialization
+ (Nikhil Sontakke)
+
+
+
+ In some cases the cache loading code would acquire share lock on a
+ system index before locking the index's catalog. This could deadlock
+ against processes trying to acquire exclusive locks in the other,
+ more standard order.
+
+
+
+
+
+ Fix dangling-pointer problem in BEFORE ROW UPDATE trigger
+ handling when there was a concurrent update to the target tuple
+ (Tom Lane)
+
+
+
+ This bug has been observed to result in intermittent cannot
+ extract system attribute from virtual tuple failures while trying to
+ do UPDATE RETURNING ctid. There is a very small probability
+ of more serious errors, such as generating incorrect index entries for
+ the updated tuple.
+
+
+
+
+
+ Disallow DROP TABLE when there are pending deferred trigger
+ events for the table (Tom Lane)
+
+
+
+ Formerly the DROP would go through, leading to
+ could not open relation with OID nnn errors when the
+ triggers were eventually fired.
+
+
+

+
+ Fix PL/Python memory leak involving array slices (Daniel Popowich)
+
+
+

+ Fix pg_restore to cope with long lines (over 1KB) in
+ TOC files (Tom Lane)

+ Support use of dlopen() in FreeBSD and OpenBSD on MIPS (Tom Lane)

+ Migration to Version 8.4.8
+
+
+ A dump/restore is not required for those running 8.4.X.
+
+
+
+ However, if your installation was upgraded from a previous major

+ Fix pg_upgrade's handling of TOAST tables
+ (Bruce Momjian)
+
+
+
+ The pg_class.relfrozenxid value for
+ TOAST tables was not correctly copied into the new installation
+ during pg_upgrade. This could later result in
+ pg_clog files being discarded while they were still
+ needed to validate tuples in the TOAST tables, leading to
+ could not access status of transaction failures.
+
+
+
+ This error poses a significant risk of data loss for installations
+ that have been upgraded with pg_upgrade. This patch
+ corrects the problem for future uses of pg_upgrade,
+ but does not in itself cure the issue in installations that have been
+ processed with a buggy version of pg_upgrade.

+ Use better SQLSTATE error codes for hot standby conflict cases
+ (Tatsuo Ishii and Simon Riggs)
+
+
+
+ All retryable conflict errors now have an error code that indicates
