Postgres 19 delayed after AI reviewers find more bugs than humans can fix
Core devs revert up to 10 features, push release to November, and blame better tooling rather than vibe coding
PostgreSQL 19, the latest version of the popular open source database, has been delayed due to the discovery of numerous bugs by AI reviewers. The release, originally scheduled for late September or early October, is now expected around November 19. Additionally, developers have dropped between eight and ten significant features, which will be postponed to the next year's release.
The delay is attributed to the limitations of LLM-assisted code reviews, which help uncover more minor issues. While these issues are easier to fix now, they have resulted in a large number of defect reports that require thorough investigation and fixing. Despite the delay, PostgreSQL 19 will still be a high-quality release, featuring REPACK CONCURRENTLY and robustness due to increased scrutiny.
The reverted features may eventually be included in PostgreSQL 20, which is now expected to have more features after this development cycle.
