Oxford, United Kingdom - August 11, 2016
Bi-Directional Replication for PostgreSQL (Postgres-BDR, or BDR) is the first open source multi-master replication system for PostgreSQL to reach full production status, developed by 2ndQuadrant and assisted by a keen user community. BDR is specifically designed for use in geographically distributed clusters, using highly efficient asynchronous logical replication, supporting anything from 2-48 nodes in a distributed database.
WHAT'S NEW?
Significant improvements related to stability and bug fixes have been made in this release. The most important factors of this release are:
- Smoother handling of schema changes (DDL) statements allowing increased operational stability and reduced maintenance.
- Various bug fixes for operational issues demonstrating high level of maturity
- Performance tuning, especially of global sequence handling
- Removal of the now deprecated UDR
- Extensive documentation improvements based upon user feedback
For a more comprehensive list of release notes, please click here: http://bdr-project.org/docs/stable/release-1.0.0.html
SUPPORT & RELEASE SCHEDULE
Postgres-BDR 9.4 1.0 will be supported until December 2019, when PostgreSQL 9.4 goes EOL. BDR continues to be developed and BDR9.6 will be released within 6 months. The BDR project has already delivered the majority of its code into PostgreSQL core, though it will likely be about 2-3 more years before this functionality is available in PostgreSQL core.
IS Postgres-BDR RIGHT FOR YOU?
BDR is well suited for databases where:
- Data is distributed globally
- Majority of data is written to from only one node at a time (For example, the US node mostly writes changes to US customers, each branch office writes mostly to branch-office-specific data, and so on.)
- There is a need for SELECTs over complete data set (lookups and consolidation)
- There are OLTP workloads with many smaller transactions
- Transactions mostly touching non overlapping sets of data
- There is partition and latency tolerance
However, this is not a comprehensive list and use cases for BDR can vary based on database type and functionality.
In addition, BDR aids business continuity by providing increased availability during network faults. Applications can be closer to the data and more responsive for users, allowing for a much more satisfying end-user experience.
PROFESSIONAL SUPPORT FOR BDR
BDR is developed and supported by 2ndQuadrant. 2ndQuadrant provides professional support for BDR, as well as consultation and training. With our deep knowledge of distributed databases, we will ensure that you are able to evaluate your use case and applications and determine the most suitable product or solution.
BDR is also available in 2ndQuadrant Cloud, initially on AWS.

Severity Rating: Critical Revision Note: V1.1 (August 11, 2016): Bulletin revised to remove Windows Server 2012 R2 (Server Core installation) from the affected software table because the Server Core version of Windows Server 2012 R2 is not affected. This is an informational change only. Customers who have already successfully installed the update do not need to take any action Summary: This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user views specially crafted PDF content online or opens a specially crafted PDF document. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. |

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
The libpq client library has also been updated to support future two-part
PostgreSQL version numbers. This update also contains tzdata release 2016f,
with updates for Kemerovo, Novosibirsk, Azerbaijan, Belarus, and Morocco.
EOL Warning for Version 9.1
PostgreSQL version 9.1 will be End-of-Life in September 2016. The project expects to only release one more update for that version. We urge users to start
planning an upgrade to a later version of PostgreSQL as soon as possible. See our
Versioning Policy for more information.
Updating
All PostgreSQL update releases are cumulative. As with other minor releases, users are not required to dump and reload their database or use pg_upgrade in order to apply this update release; you may simply shut down PostgreSQL and update its binaries. Users who have skipped one or more update releases may need to run additional, post-update steps; please see the release notes for earlier versions for details.

The PostgreSQL Global Development Group announces today that the fourth beta release of PostgreSQL 9.6 is available for download. This release contains previews of all of the features which will be available in the final release of version 9.6, including fixes to many of the issues found in the first and second betas. Users are encouraged to continue testing their applications against 9.6 beta 4.
Changes Since Beta 3
9.6 Beta 4 includes the security fixes in the 2016-08-11 Security Update, as well as the general bug fixes offered for stable versions. Additionally, it contains fixes for the following beta issues reported since the last beta:
- Change minimum max_worker_processes from 1 to 0
- Make array_to_tsvector() sort and de-duplicate the given strings
- Fix ts_delete(tsvector, text[]) to cope with duplicate array entries
- Fix hard to hit race condition in heapam's tuple locking code
- Prevent "snapshot too old" from trying to return pruned TOAST tuples
- Make INSERT-from-multiple-VALUES-rows handle targetlist indirection
- Do not let PostmasterContext survive into background workers
- Add missing casts in information schema
- Fix assorted problems in recovery tests
- Block interrupts during HandleParallelMessages()
- Remove unused arguments from pg_replication_origin_xact_reset function
- Correctly handle owned sequences with extensions
- Many fixes for tsqueue.c
- Eliminate a few more user-visible "cache lookup failed" errors
- Teach parser to transform "x IS [NOT] DISTINCT FROM NULL" to a NullTest
- Allow functions that return sets of tuples to return simple NULLs
- Repair damage done by citext--1.1--1.2.sql
- Correctly set up aggregate FILTER expression in partial-aggregation plans
This beta also includes many documentation updates and improvements.
Due to changes in system catalogs, a pg_upgrade or pg_dump and restore will be required for users migrating databases from earlier betas.
Note that some known issues remain unfixed. Before reporting a bug in the beta, please check the Open Items page.
Beta Schedule
This is the fourth beta release of version 9.6. The PostgreSQL Project will release additional betas as required for testing, followed by one or more release candidates, until the final release in late 2016. For further information please see the Beta Testing page.
