78eee1bf9f The PostgreSQL Global Development Group has released a security update to all current versions of the PostgreSQL database system, including versions 9.2.3, 9.1.8, 9.0.12, 8.4.16, and 8.3.23. This update fixes a denial-of-service (DOS) vulnerability. All users should update their PostgreSQL installations as soon as possible.
The security issue fixed in this release, CVE-2013-0255, allows a previously authenticated user to crash the server by calling an internal function with invalid arguments. This issue was discovered by independent security researcher Sumit Soni this week and reported via Secunia SVCRP, and we are grateful for their efforts in making PostgreSQL more secure.

Today's update also fixes a performance regression which caused a decrease in throughput when using dynamic queries in stored procedures in version 9.2. Applications which use PL/pgSQL's EXECUTE are strongly affected by this regression and should be updated. Additionally, we have fixed intermittent crashes caused by CREATE/DROP INDEX CONCURRENTLY, and multiple minor issues with replication.

This release is expected to be the final update for version 8.3, which is now End-of-Life (EOL). Users of version 8.3 should plan to upgrade to a later version of PostgreSQL immediately. For more information, see our Versioning Policy.

This update release also contains fixes for many minor issues discovered and patched by the PostgreSQL community in the last two months, including:

* Prevent unnecessary table scans during vacuuming
* Prevent spurious cached plan error in PL/pgSQL
* Allow sub-SELECTs to be subscripted
* Prevent DROP OWNED from dropping databases or tablespaces
* Make ECPG use translated messages
* Allow PL/Python to use multi-table trigger functions (again) in 9.1 and 9.2
* Fix several activity log management issues on Windows
* Prevent autovacuum file truncation from being cancelled by deadlock_timeout
* Make extensions build with the .exe suffix automatically on Windows
* Fix concurrency issues with CREATE/DROP DATABASE
* Reject out-of-range values in to_date() conversion function
* Revert cost estimation for large indexes back to pre-9.2 behavior
* Make pg_basebackup tolerate timeline switches
* Cleanup leftover temp table entries during crash recovery
* Prevent infinite loop when COPY inserts a large tuple into a table with a large fillfactor
* Prevent integer overflow in dynahash creation
* Make pg_upgrade work with INVALID indexes
* Fix bugs in TYPE privileges
* Allow Contrib installchecks to run in their own databases
* Many documentation updates
* Add new timezone "FET".

f3c67e2efa Changes 9.0.2:
* Force the default wal_sync_method to be fdatasync on Linux
* Fix "too many KnownAssignedXids" error during Hot Standby replay
* Fix race condition in lock acquisition during Hot Standby
* Avoid unnecessary conflicts during Hot Standby

  immediately after creating the master database cluster
* Fix persistent slowdown of autovacuum workers when multiple workers
  remain active for a long time
* Fix long-term memory leak in autovacuum launcher
* Avoid failure when trying to report an impending transaction
  wraparound condition from outside a transaction
* Add support for detecting register-stack overrun on IA64
* Add a check for stack overflow in copyObject()
* Fix detection of page splits in temporary GiST indexes
* Fix error checking during early connection processing
* Improve efficiency of window functions
* Avoid memory leakage while "ANALYZE"'ing complex index expressions
* Ensure an index that uses a whole-row Var still depends on its table
* Add missing support in "DROP OWNED BY" for removing foreign data
  wrapper/server privileges belonging to a user
* Do not "inline" a SQL function with multiple OUT parameters

  list contains a reference to an inline-able user function

  PL/pgSQL now treats all core reserved words as reserved.
