The PostgreSQL Global Development Group has released an update to all supported versions of PostgreSQL, including 14.5, 13.8, 12.12, 11.17, and 10.22, as well as the third beta release of PostgreSQL 15. This release closes one security vulnerability and fixes over 40 bugs reported over the last three months.
For the full list of changes, please review the release notes.
PostgreSQL 10 will stop receiving fixes on November 10, 2022. If you are running PostgreSQL 10 in a production environment, we strongly advise that you make plans to upgrade to a newer, supported version of PostgreSQL so you can continue to receive bug and security fixes. Please see our versioning policy for more information.
Versions Affected: 10 - 14. The security team typically does not test unsupported versions, but this problem is quite old.
Some extensions use
CREATE OR REPLACE or
CREATE IF NOT EXISTS commands.
However, some don't adhere to the documented rule to target only objects known
to be extension members already. An attack requires permission to create
non-temporary objects in at least one schema, ability to lure or wait for an
administrator to create or update an affected extension in that schema, and
ability to lure or wait for a victim to use the object targeted in
CREATE OR REPLACE or
CREATE IF NOT EXISTS.
Given all three prerequisites, the attacker can run arbitrary code as the victim role, which may be a superuser. Known-affected extensions include both PostgreSQL-bundled and non-bundled extensions. PostgreSQL blocks this attack in the core server, so there's no need to modify individual extensions.
The PostgreSQL project thanks Sven Klemm for reporting this problem.
This release marks the third beta release of PostgreSQL 15 and puts the community one step closer to general availability tentatively around the end of the third quarter.
In the spirit of the open source PostgreSQL community, we strongly encourage you to test the new features of PostgreSQL 15 on your systems to help us eliminate bugs or other issues that may exist. While we do not advise you to run PostgreSQL 15 Beta 3 in production environments, we encourage you to find ways to run your typical application workloads against this beta release.
Your testing and feedback will help the community ensure that PostgreSQL 15 upholds our standards of delivering a stable, reliable release of the world's most advanced open source relational database. Please read more about our beta testing process and how you can contribute:
You can find information about all of the PostgreSQL 15 features and changes in the release notes:
This update fixes over 40 bugs that were reported in the last several months. The issues listed below affect PostgreSQL 14. Some of these issues may also affect other supported versions of PostgreSQL.
Included in this release:
CREATE DATABASEwrite-ahead log (WAL) records on standby servers when encountering a missing tablespace directory.
CREATE INDEXto use the user's permissions. This fixes broken dump/restore scenarios that relied on the behavior prior to the fix for CVE-2022-1552.
CREATE DATABASEand other commands that can't run in a transaction block.
= ANY(array)clauses when there are MCV-type extended statistics on the
ANALYZEwhile it is computing extended statistics.
ALTER TABLE ... ENABLE/DISABLE TRIGGERto handle recursion for triggers on partitioned tables.
ROW()expressions and functions in
FROMthat have more than 1600 columns.
SPI_commit(), rather than expecting callers to do that. This includes a fix for the same scenario in PL/Python, which had reported crashes on Python 3.11 and memory leaks on older versions of Python 3.
libpqof idle states in pipeline mode.
\watchcommand, echo a newline after cancellation with control-C.
pg_upgradeto detect non-upgradable usages of functions accepting
postgres_fdwfixes, including prevention of batch insertions when there are
WITH CHECK OPTIONconstraints present.
For the full list of changes available, please review the release notes.
All PostgreSQL update releases are cumulative. As with other minor releases,
users are not required to dump and reload their database or use
order to apply this update release; you may simply shutdown 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.
For more details, please see the release notes.
To upgrade to PostgreSQL 15 Beta 3 from Beta 2, Beta 1, or an earlier version of
PostgreSQL, you will need to use a strategy similar to upgrading between
major versions of PostgreSQL (e.g.

The stability of each PostgreSQL release greatly depends on you, the community, to test the upcoming version with your workloads and testing tools to find bugs and regressions before the general availability of PostgreSQL 15. As this is a beta release, changes to database behaviors, feature details, and APIs are still possible. Your feedback and testing will help determine the final tweaks on the new features, so please test in the near future. The quality of user testing helps determine when we can make a final release.
