lwn.net by jzb 4 min read Editor score 7/10

PostgreSQL’s beta has seen features reverted over architectural flaws and a long tail of edge-case defects, with LLM-assisted review surfacing issues faster. The resulting workload shows how stronger automated review can raise quality bars while increasing release-management costs.

What

- PostgreSQL 19 has seen an unusually high number of feature reverts since beta began.

How

- LLM-assisted review surfaced many edge-case defects quickly; handling each report has fixed overhead and consumed limited time.

Why it matters

- Faster review can raise the effective quality bar for committed features, increasing stabilization workload during beta.
