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 4 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:

Upgrading to PostgreSQL 15 Beta 4
To upgrade to PostgreSQL 15 Beta 4 from an earlier beta or previous 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.

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 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.
