The PostgreSQL Global Development Group announces that the fourth beta release of PostgreSQL 11 is now available for download. This release contains previews of all features that will be available in the final release of PostgreSQL 11 (though some details could change before a release candidate is made available) as well as bug fixes that were reported during the third beta.
This is likely the last beta release for PostgreSQL 11 before a release candidate is made available.
In the spirit of the open source PostgreSQL community, we strongly encourage you to test the new features of PostgreSQL 11 in your database systems to help us eliminate any bugs or other issues that may exist.
To upgrade to PostgreSQL 11 Beta 4 from Beta 3 or an earlier version of
PostgreSQL 11, you will need to use a strategy similar to upgrading between
major versions of PostgreSQL (e.g.

There have been many bug fixes for PostgreSQL 11 reported during the Beta 3 period and applied to the Beta 4 release. This release also includes other bug fixes that were reported for supported versions of PostgreSQL that also affected PostgreSQL 11. These fixes include:
jit = on in your configuration file or in a session
CREATE INDEX by disallowing builds on mapped catalog
XMLTABLE in a single query
libpq, including a fix to only look up a hostname when
explicitly requested to do so
pg_upgrade fixes, including handling event triggers in extensions
For a detailed list of fixes, please visit the open items page.
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 release of PostgreSQL 11. 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.
This is the fourth beta release of PostgreSQL 11. In all likelihood, this is the final beta release of PostgreSQL 11 before one or more release candidates are made available. For further information please see the Beta Testing page.
