HN thread on pgrust questions AI-assisted rewrites and test-based reliability

Category: Pulse
Status: discussion
Sources: HN discussion
Summary: The 451-comment thread on pgrust (covered in Top stories) surfaces a recurring argument about database reliability.
Comments: Commenters distinguish a hand-written rewrite from an AI-assisted one and argue that databases like PostgreSQL and SQLite earn reliability from years of production exposure and real-world failure handling, not from passing a regression suite. Others debate the AGPL-3.0 license choice for a drop-in Postgres reimplementation.
Why it matters: The thread captures how practitioners weigh a passing test suite against production hardening when judging a systems rewrite.
