Vibe Hacking Postgres
Merge improvements into commit-LSN logging for destructive DDL.
session summary
The session opened with AI-assisted Postgres development lessons from the committed pg_dump policy patch and a separate wal_compression-level prototype: write tests and documentation early, review every line, and use several strong models as independent critics. The practical task was merging Jim Jones's improvements into the patch that logs commit LSNs for destructive DDL. Cursor produced overbroad changes, but after resetting and supplying both patches, the group compiled and manually tested the result, found a callback-unregistration bug, and attempted test-driven repair.
