Three major features, UPDATE/DELETE FOR PORTION OF, SQL/PGQ, and ALTER TABLE MERGE/SPLIT PARTITION, were reverted between August 27 and September 15. Back-patched commits to REL_19_STABLE jumped more than 60% compared to the prior year's cycle, and back-patches to the previous stable release jumped over 74%. LLM-drafted fixes still need human review, which slowed the release process. Haas calls the delay not concerning, since it reflects the project's focus on quality. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### why is PostgreSQL 19 release delayed PostgreSQL 19 is delayed past its usual September-October window and most likely won't ship until November because LLMs are finding bugs in the codebase faster than committers can fix and review them. Back-patched commits jumped more than 60% year over year, diverting reviewer time and forcing three major features to be reverted late in the beta period. _Tracking a major database release slip? Follow PostgreSQL 19 developments as they land on daily.dev._ ### which features were reverted from PostgreSQL 19 beta Three major features were pulled from PostgreSQL 19 between August 27 and September 15: UPDATE/DELETE FOR PORTION OF, SQL Property Graph Queries (SQL/PGQ), and ALTER TABLE MERGE PARTITION/SPLIT PARTITION. All three were reverted late in the beta cycle, which is unusual compared to prior years' feature-freeze-adjacent reverts. _Developers planning around these partition and graph query features can watch for updates on daily.dev._ ### how many bugs are LLMs finding in open source codebases like PostgreSQL A large increase: back-patched commits to PostgreSQL's prior stable release jumped more than 74% in a single year, and back-patches to the in-progress release rose over 60%, attributed to people using LLMs to find and report bugs. LLMs can draft fixes, but those drafts still require human review since they aren't always correct or standards-compliant. _Anyone weighing AI-assisted bug hunting against maintainer bandwidth can follow this trend on daily.dev._ --- Tags: [#open-source](https://daily.dev/tags/open-source), [#postgresql](https://daily.dev/tags/postgresql), [#ai-coding](https://daily.dev/tags/ai-coding) [View this post on daily.dev](https://daily.dev/posts/postgres-19-is-late-and-it-s-ai-s-fault-4maw4xj9t) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Postgres 19 is late, and it's AI's fault","url":"https://daily.dev/posts/postgres-19-is-late-and-it-s-ai-s-fault-4maw4xj9t","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/postgres-19-is-late-and-it-s-ai-s-fault-4maw4xj9t"},"datePublished":"2026-10-23T05:44:03.356Z","dateModified":"2026-10-23T05:44:33.926Z","description":"PostgreSQL 19 is delayed until November because LLMs are finding bugs faster than committers can fix them, Robert Haas writes.
