PostgreSQL 19 has slipped from its planned late-September/early-October release to around November 19, and the next version of the open-source database will ship without 8–10 features originally slated for it. The PostgreSQL Global Development Group pulled the features after LLM-assisted code review turned up a long tail of edge-case defects that developers did not have time to resolve during beta.
According to Peter Eisentraut, a PostgreSQL committer and EDB vice president, the AI-supported reviews became more useful in the months before launch, effectively raising the quality bar after much of the new code had already been written and committed. He described the result as a list of dozens of defect reports, each small on its own but carrying a fixed overhead that exhausted the team's time. Among the postponed features is support for SQL Property Graph Queries (SQL/PGQ), which contributor Tom Lane had warned was risky to ship in v19.
Eisentraut was careful to say the reverts were not due to "vibe coding," since most features were written before such techniques were available. He promised PostgreSQL 19 will still be a strong release, noting REPACK CONCURRENTLY as a way to reclaim disk space without VACUUM FULL's table lock, and said the extra scrutiny should make it robust. The reverted features are expected to land in PostgreSQL 20, which was previously expected to contain only bug fixes.
