PostgreSQL 19 Running Behind Schedule Due to AI/LLM Burden

PostgreSQL 19, typically released every September–October, will not arrive until at least November this year because developers have been overwhelmed by increased bug reports and patches from AI/LLM activity. Developer Robert Haas said LLM-drafted fixes still require human review and commitment, and time that would have gone to reviewing release contents was diverted to security issues and back-branch bugs, delaying decisions on what needed reverting before shipping v19.
