Fact: On 24 September 2026, the PostgreSQL project released the fourth beta of version 19. It removed several features, including SQL/PGQ graph queries, changes to temporal table ranges using FOR PORTION OF, partition merge and split operations, and online enabling of data checksums. The project said these features need more work; version 19 is not yet a production release.

What it means for an architect — interpretation

If an HLD or delivery plan depends on a beta feature, mark it as “confirm in GA” and prepare a route that does not rely on it. Before deciding on a migration, compare the final release notes, application compatibility and restore procedures. A feature present in an earlier beta is not guaranteed in the final release.

Question for your project

Which decisions in our plan depend on PostgreSQL 19 features, and what will we do if they do not ship in the final release?
