PostgreSQL 17.4, 16.8, 15.12, 14.17, and 13.20 Released!

The PostgreSQL Global Development Group has released an update to all supported versions of PostgreSQL, including 17.4, 16.8, 15.12, 14.17, and 13.20.

For the full list of changes, please review the  release notes.

Bug Fixes and Improvements

The issues listed below affect PostgreSQL 17. Some of these issues may also affect other supported versions of PostgreSQL.

• Improve behavior of quoting functions in  libpq. The fix for  CVE-2025-1094 caused the quoting functions to not honor their string length parameters and, in some cases, cause crashes. This problem could be noticeable from a PostgreSQL client library, based on how it is integrated with libpq.
• Fix small memory leak in  pg_createsubscriber.

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 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 from earlier versions for details.

For more details, please see the  release notes.
