The PostgreSQL Global Development Group has released an update to all supported versions of our database system, including 9.5.4, 9.4.9, 9.3.14, 9.2.18 and 9.1.23. This release fixes two security issues. It also patches a number of other bugs reported over the last three months. Users who rely on security isolation between database users should update as soon as possible. Other users should plan to update at the next convenient downtime.

Security Issues
---------------
Two security holes have been closed by this release:

CVE-2016-5423: certain nested CASE expressions can cause the server to crash.
CVE-2016-5424: database and role names with embedded special characters can allow code injection during administrative operations like pg_dumpall.
The fix for the second issue also adds an option, -reuse-previous, to psql's \connect command. pg_dumpall will also refuse to handle database and role names containing line breaks after the update. For more information on these issues and how they affect backwards-compatibility, see the Release Notes.

Bug Fixes and Improvements
--------------------------
This update also fixes a number of bugs reported in the last few months. Some of these issues affect only version 9.5, but many affect all supported versions:

Fix misbehaviors of IS NULL/IS NOT NULL with composite values
Fix three areas where INSERT ... ON CONFLICT failed to work properly with other SQL features.
Make INET and CIDR data types properly reject bad IPv6 values
Prevent crash in "point ## lseg" operator for NaN input
Avoid possible crash in pg_get_expr()
Fix several one-byte buffer over-reads in to_number()
Don't needlessly plan query if WITH NO DATA is specified
Avoid crash-unsafe state in expensive heap_update() paths
Fix hint bit update during WAL replay of row locking operations
Avoid unnecessary "could not serialize access" with FOR KEY SHARE
Avoid crash in postgres -C when the specified variable is a null string
Fix two issues with logical decoding and subtransactions
Ensure that backends see up-to-date statistics for shared catalogs
Prevent possible failure when vacuuming multixact IDs in an upgraded database
When a manual ANALYZE specifies columns, don't reset changes_since_analyze
Fix ANALYZE's overestimation of n_distinct for columns with nulls
Fix bug in b-tree mark/restore processing
Fix building of large (bigger than shared_buffers) hash indexes
Prevent infinite loop in GiST index build with NaN values
Fix possible crash during a nearest-neighbor indexscan
Fix "PANIC: failed to add BRIN tuple" error
Prevent possible crash during background worker shutdown
Many fixes for issues in parallel pg_dump and pg_restore
Make pg_basebackup accept -Z 0 as no compression
Make regression tests safe for Danish and Welsh locales

Changes:
This release primarily fixes issues not successfully fixed in prior releases. It should be applied as soon as possible all users of major versions 9.3 and 9.4. Other users should apply at the next available downtime.

Crash Recovery Fixes:
Earlier update releases attempted to fix an issue in PostgreSQL 9.3 and 9.4 with "multixact wraparound", but failed to account for issues doing multixact cleanup during crash recovery. This could cause servers to be unable to restart after a crash. As such, all users of 9.3 and 9.4 should apply this update as soon as possible.

The PostgreSQL Global Development Group has released an update to all supported version of the database system, including versions 9.3.5, 9.2.9, 9.1.14, 9.0.18, and 8.4.22. This minor release fixes a number of issues discovered and reported by users over the last four months, including some data corruption issues, and is the last update of version 8.4. Users of version 9.3 will want to update at the earliest opportunity; users of version 8.4 will want to schedule an upgrade to a supported PostgreSQL version.

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".

Version 9.1 delivers several features which users have been requesting for
years, removing roadblocks to deploying new or ported applications on
PostgreSQL. These include:
* Synchronous Replication: enable high-availability with consistency across
  multiple servers
* Per-Column Collations: support linguistically-correct sorting per database,
  table or column.
* Unlogged Tables: greatly improves performance for ephemeral data

Our community of contributors innovates with cutting-edge features. Version 9.1
includes several which are new to the database industry, such as:
* K-Nearest-Neighbor Indexing: index on "distance" for faster location and text
  search queries
* Serializable Snapshot Isolation: keeps concurrent transactions consistent
  without blocking, using "true serializability"
* Writeable Common Table Expressions: execute complex multi-stage data updates
  in a single query
* Security-Enhanced Postgres: deploy military-grade security and Mandatory
  Access Control
