Vibe Hacking Postgres
Add a pg_resetwal system-identifier option and audit the agentic patch workflow.
session summary
Nik presented an AI-assisted pg_resetwal option for changing the system identifier, needed to replay archived WAL after DBLab created a replacement cluster. Review accepted the use case but called for removing interactive safeguards, shortening documentation, reducing redundant tests, and aligning option identifiers with other frontend tools. The session then demonstrated Nik's agentic patch workflow: small commits, specification-first documentation, compilation and manual tests, strict review by stronger models, and a final human review that caught issues the models missed.
