The PostgreSQL Global Development Group announces that the second beta release of PostgreSQL 19 is now available for download. This release contains PostgreSQL 19 feature previews ahead of general availability, though some details of the release can change during the beta period.
You can find information about all of the PostgreSQL 19 features and changes in the release notes:
https://www.postgresql.org/docs/19/release-19.html
In the spirit of the open source PostgreSQL community, we strongly encourage you to test the new features of PostgreSQL 19 on your systems to help us eliminate bugs and other issues. While we do not advise you to run beta versions in production environments, we encourage you to find ways to run your typical application workloads against this beta release.
Your testing and feedback help the community ensure that PostgreSQL 19 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:

To upgrade to PostgreSQL 19 Beta 2 from 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.
Fixes and changes in PostgreSQL 19 Beta 2 include:
vacuumdb --analyze-in-stages for partitioned tables.servicefile to show correct file after fallback to system file.pg_createsubscriber to accept duplicate publication names.REPACK worker not being cleaned up on a FATAL exit.FOR PORTION OF temporal table syntax.max_retention_duration.md5_password_warnings for role and database settings.pg_dumpall.ALTER DOMAIN ... VALIDATE CONSTRAINT.postgres_fdw handles imported foreign-table statistics.Please see the release notes for a complete list of new and changed features:
https://www.postgresql.org/docs/19/release-19.html
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 19. As this is a Beta, minor 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.
