The Hitchhiker’s Guide to PostgreSQL Hacking: Don’t Panic, Just Start Small | POSETTE 2026
A practical guide on getting started with PostgreSQL hacking by starting small with patch reviews and bug fixes.
“Do not try to understand everything first. Start with something small enough to finish.”
A POSETTE 2026 conference talk by a speaker named Xuneng offers practical advice for newcomers to contribute to PostgreSQL by reviewing patches, fixing bugs, and testing features. It walks through a real review journey of a WAL LSN replay feature addressing read-after-write consistency in async replication. The talk is about open-source database engineering, not AI, so it carries little relevance as an AI industry signal.
