He attributes much of this to LLM-assisted code review surfacing latent defects, including architectural issues and a long tail of edge-case bugs, far faster than traditional review would have historically. Since fixing dozens of defect reports under beta time constraints wasn't feasible, many affected features—mostly written before LLM-assisted review was effective—were pulled instead. He clarifies this is not a result of 'vibe coding,' since the code predates that practice, but rather a retroactively raised quality bar now being applied to older contributions. ## Full article daily.dev links to this article rather than hosting it.

PostgreSQL core team member Peter Eisentraut attributes the reverts to LLM-assisted code review surfacing defects much faster than traditional methods, including architectural flaws and dozens of edge-case bugs in older code. Since fixing around forty defect reports with a fixed per-issue overhead wasn't feasible during beta, maintainers pulled the affected features instead. He notes this is unrelated to vibe coding, since the code predates that practice. _Developers tracking PostgreSQL 19's beta changes can follow release stability updates on daily.dev._ ## Similar posts on daily.dev - [Why PostgreSQL needs an AI usage policy](https://daily.dev/posts/why-postgresql-needs-an-ai-usage-policy-nsinedikt) · Planet PostgreSQL · 0 upvotes · 0 comments --- Tags: [#postgresql](https://daily.dev/tags/postgresql), [#code-review](https://daily.dev/tags/code-review) [View this post on daily.dev](https://daily.dev/posts/eisentraut-the-reverts-will-continue-until-morale-improves-1b6fogwm2) ```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":"Eisentraut: The reverts will continue until morale improves","url":"https://daily.dev/posts/eisentraut-the-reverts-will-continue-until-morale-improves-1b6fogwm2","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/eisentraut-the-reverts-will-continue-until-morale-improves-1b6fogwm2"},"datePublished":"2026-10-13T13:24:37.696Z","dateModified":"2026-10-19T15:21:36.956Z","description":"PostgreSQL core team member Peter Eisentraut reflects on why an unusually high number of features have been reverted from the upcoming PostgreSQL 19 release...","image":"https://media.daily.dev/image/upload/s--VDukGCjf--/f_auto/v1722860399/public/Placeholder%2002","thumbnailUrl":"https://media.daily.dev/image/upload/s--VDukGCjf--/f_auto/v1722860399/public/Placeholder%2002","isAccessibleForFree":true,"articleSection":"LWN.net","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"LWN.net","logo":"https://media.daily.dev/image/upload/s--4jjE7GIK--/f_auto,q_auto/v1774960833/logos/lwn?_a=BAMAMiWQ0","url":"https://daily.dev/sources/lwn"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/eisentraut-the-reverts-will-continue-until-morale-improves-1b6fogwm2","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"postgresql,code-review","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"LWN.net","item":"https://daily.dev/sources/lwn"},{"@type":"ListItem","position":3,"name":"Eisentraut: The reverts will continue until morale improves"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/eisentraut-the-reverts-will-continue-until-morale-improves-1b6fogwm2#faq","mainEntity":[{"@type":"Question","name":"Why were so many features reverted from PostgreSQL 19 during its beta period?","acceptedAnswer":{"@type":"Answer","text":"PostgreSQL core team member Peter Eisentraut attributes the reverts to LLM-assisted code review surfacing defects much faster than traditional methods, including architectural flaws and dozens of edge-case bugs in older code.
