PostgreSQL releases fourth beta of version 19

The PostgreSQL Global Development Group announced PostgreSQL 19 Beta 4 on September 24, 2026, and said the build is available to download. The beta previews features planned for PostgreSQL 19 ahead of general availability, but the project says details may change as testing proceeds. The release notes describe the features and changes included in the preview. For teams assessing the next version, the announcement provides a test build and a reference for what is currently included, rather than a final specification.

The project is encouraging users to try the new features on their systems to help find bugs and other issues. It also asks users to run their typical application workloads against the beta. The stated goal is to use testing and feedback to help deliver a stable release. The project points readers to information about its testing process and ways to contribute, giving developers a path to share what they find.

For builders evaluating a database-backed application, including AI products, the request offers a practical testing target: check how the application behaves with the preview using its usual workloads. The release notes can help developers identify which changes to examine, while the project’s testing guidance explains how to contribute feedback. Because this is a beta and details can change, test results apply to the preview rather than establishing how the final release will behave. PostgreSQL explicitly advises against running beta versions in production environments.

The announcement also gives a separate support notice for PostgreSQL 14 users: that version will stop receiving fixes on November 12, 2026. The project recommends that organizations running PostgreSQL 14 in production plan to move to a newer supported version. This notice concerns PostgreSQL 14, not the PostgreSQL 19 beta, and the project refers users to its versioning policy for more information. For teams maintaining application databases, the two items call for distinct work: evaluate PostgreSQL 19 outside production and plan around the stated end of fixes for PostgreSQL 14.
