PostgreSQL 19 is delayed due to an influx of LLM-found bug reports
PostgreSQL 19 will miss its usual September to mid-October release window and is not expected to ship until November 2026, or possibly later. According to a PostgreSQL developer writing on the Neon blog, the delay follows a surge in bug reports surfaced by large language models, alongside the late reversion of major features including SQL Property Graph Queries, UPDATE/DELETE FOR PORTION OF, and…
Key points
- PostgreSQL 19 is delayed until at least November 2026 following late feature reversions between August 27 and September 15.
- Back-patched commits to prior release branches rose more than 74% year over year between April 8 and September 25.
- A contributor attributes the backlog to users employing LLMs to find bugs across PostgreSQL's forty-year-old code base.
The project experienced a major increase in back-patched bug fixes. Between April 8 and September 25, commits back-patched to the in-progress release branch rose by more than 60% year over year, while commits back-patched to older branches jumped over 74%. The author attributes this to outside users using LLMs to scan decades of existing code, uncovering defects faster than maintainers can review and fix them.
While AI can generate potential fixes, maintainers must still verify that solutions meet project standards. The author notes that diverting developer time toward handling these issues and back-branch bugs slowed the review of new features, though the author views the delay as a manageable trade-off to maintain code quality.
Postgres 19 is late, and it's AI's fault
