Agentic Hacking Postgres with Andrey, Kirk, and Nik
Review the PG20-2 backlog: minor upgrades, global temporary tables, wait instrumentation, and pg_stat_log.
The group turned a tour of the PG20-2 CommitFest into concrete review homework. They reconciled Andrey Borodin's prolific August as 25 currently authored entries, explored bounded pre-shutdown checkpoints and safe cache handoff for minor upgrades, and examined why global temporary tables require deep catalog, relcache, planner, statistics, and lifecycle work. They then compared Ilmar Yunusov's EXPLAIN wait-event patch with Dmitry Fomin's broader timing/tracing series, insisting on honest attribution and workload benchmarks. The most actionable outcome was pg_stat_log: Nikolay will independently benchmark and review its SQL-queryable error counters, Kirk will support the thread, Andrey will revisit Dmitry's series, and Kirk will revise his pg_dump placeholder interface.
