PostgreSQL Committer: LLM Review Found More Bugs in Version 19 Than Could Be Fixed

The release of PostgreSQL 19 has been postponed to November 19, despite initial expectations for a late September or early October launch. According to Peter Eisentraut, a leading project committer at EDB, the delay is partly attributed to the integration of Large Language Model (LLM) tools for code review. The use of AI uncovered significantly more bugs in the upcoming version than the development team could address by the original deadline. Consequently, to ensure the stability and quality of the release, it was decided to remove 8 to 10 major features from PostgreSQL 19. This incident highlights the growing role of automated code analysis systems in the development of large open-source projects, where the complexity of the codebase necessitates new approaches to quality control and testing before updates are released.
