The PostgreSQL Global Development Group announces that the second beta release of PostgreSQL 14 is now available for download. This release contains previews of all features that will be available in the final release of PostgreSQL 14, though some details of the release could change before then.

You can find information about all of the features and changes found in PostgreSQL 14 in the release notes:

In the spirit of the open source PostgreSQL community, we strongly encourage you to test the new features of PostgreSQL 14 in your systems to help us eliminate any bugs or other issues that may exist. While we do not advise you to run PostgreSQL 14 Beta 2 in your production environments, we encourage you to find ways to run your typical application workloads against this beta release.

Upgrading to PostgreSQL 14 Beta 2

To upgrade to PostgreSQL 14 Beta 2 from 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. pg_upgrade or pg_dump / pg_restore). For more information, please visit the documentation section on upgrading.

Changes Since Beta 1

There have been many bug fixes for PostgreSQL 14 reported during the Beta 1 period and applied to the Beta 2 release. This includes:

  • Redesign the handling of OUT parameters for procedures.
  • Various improvements and fixes to LZ4 support for toast columns.
  • Support disabling index bypassing by VACUUM.
  • Addition of --no-toast-compression to pg_dumpall
  • Fix a crash in libpq with SSL SNI when specifying hostaddr in connection string.
  • Fix assertion failure when streaming multi-INSERT data in logical replication.
  • Fix portability issue with the function permute in pgbench.
  • Fix postgres_fdw failures with whole-row Vars.
  • Fix several issues with pg_stat_wal.

Please see the release notes for a complete list of new and changed features:

Testing for Bugs & Compatibility

The stability of each PostgreSQL release greatly depends on you, the community, to test the upcoming version with your workloads and testing tools in order to find bugs and regressions before the general availability of PostgreSQL 14. As this is a Beta, 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.

A list of open issues is publicly available in the PostgreSQL wiki. You can report bugs using this form on the PostgreSQL website:

Beta Schedule

This is the second beta release of version 14. The PostgreSQL Project will release additional betas as required for testing, followed by one or more release candidates, until the final release in late 2021. For further information please see the Beta Testing page.
