Postgres 19 is late, and it's AI's fault

PostgreSQL 19 is expected to miss its usual mid-October release window and may not ship until November, largely because LLM-assisted bug discovery has sharply increased the volume of issues requiring human review and fixes. Several major features, including SQL Property Graph Queries and partition-management capabilities, were reverted late in beta testing as developers focused on correctness and security. Commit data shows substantial growth in back-patched fixes for both the in-progress release and older supported versions, which the author attributes primarily to more bugs being uncovered rather than declining developer quality. Although the immediate delay is presented as a reasonable quality-focused decision, the author raises longer-term concerns about whether PostgreSQL’s limited pool of maintainers can keep pace with decades of newly discoverable defects while continuing to develop new features.
