PostgreSQL 19 drops features after AI checks find defects
Bug reports from AI-assisted code checking arrived faster than developers could fix them, so the database ships later and with less.
The next PostgreSQL, one of the most widely used open-source databases, arrives late and lighter. Its developers have pulled eight to 10 major features from version 19 and moved the launch to around 19 November 2026, The Register reported on Friday 16 October. The release had been due in late September or early October.
AI is part of the story. Code checks run with large language models, the technology behind chatbots, now surface in months the flaws that used to take years to appear, core developer Peter Eisentraut writes. Forty bug reports can land in one go. Even small fixes each need someone to read, patch and check them.
A few of the pulled features were flawed at the design level, too big a job for a beta. One is SQL Property Graph Queries, a way to search data as a network of linked records, The Register reports. The Register says the pulled work moves to PostgreSQL 20.
Most of that code was written before AI-assisted checking was available, he says, so it now meets a higher bar than when it went in. He names other causes too, among them security work that took senior developers away from the beta.
AI tools that find bugs faster also create a queue of fixes: build that time into any release date.
