PostgreSQL 19 Delayed as AI-Generated Bug Reports Overwhelm Developers

PostgreSQL usually ships its yearly feature release in September or October. This year the schedule has slipped: PostgreSQL 19 will arrive in November at the earliest, and possibly later.

PostgreSQL developer Robert Haas explained the delay in a blog post. According to him, the team has been swamped by a surge of bug reports coming from AI agents built on large language models. At the same time, developers have had to back-port bug and security fixes to earlier PostgreSQL versions.

Two factors

Haas believes this accounts both for the many late reverts and for the delay of the release itself. He points to two causes.

First, far more bugs are being found now, so fixing them takes more time. LLMs can draft fixes, but those patches are not always correct or compliant with PostgreSQL's standards. They still have to be reviewed and committed by humans, and those humans, Haas notes dryly, have not gotten any smarter between 2025 and 2026.

Second, time that would normally go into reviewing what went into the release was diverted to addressing security issues and other bugs in the back-branches. As a result, it took longer to work out which changes had to be reverted before shipping version 19.

Not an isolated case

The PostgreSQL situation fits a broader pattern: open-source maintainers increasingly complain that AI tooling activity puts a load on them comparable to a denial-of-service attack. AI finds bugs faster, but people still have to sort through the findings, and their capacity has not grown.
