The PostgreSQL Global Development Group has announced the availability of PostgreSQL 19 Beta 4, the fourth beta release of the upcoming major version. This release provides a preview of PostgreSQL 19 features ahead of general availability, but some details may change during the beta period. The release notes document all features and changes.
The next planned release is the release candidate, expected in early October. Based on testing and evaluation, the general availability (GA) of PostgreSQL 19 may also occur in October. More details will be provided as these releases approach.
A key aspect of this beta release is that it reverts several features that were originally planned for PostgreSQL 19. The PostgreSQL community strongly believes that PostgreSQL must be reliable first and foremost. Additionally, the community strives for a predictable release schedule. Consequently, the community chose to remove some features from the PostgreSQL 19 release so they can potentially be included in a later major release after more time working through the community development and review process.
- Reverted features that were originally planned for PostgreSQL 19.
- Reverted features may be included in a later major release.
- The next release is the release candidate, expected in early October.
- General availability may also occur in October.
For developers, this beta release underscores the community's commitment to reliability and predictability over adding new features hastily. It means that some anticipated features may not be available in PostgreSQL 19, but they are likely to be revisited in future versions. Developers should test this beta release and provide feedback to help shape the final release. The release notes provide comprehensive information on all changes.
