Postgres Book: A Topic-by-Topic Guide to PostgreSQL
Content is AI-assisted and may contain inaccuracies.
Postgres Book is a free, open-source learning resource that covers PostgreSQL one topic at a time instead of presenting a single large manual. Each topic explains how a mechanism works and expects the reader to run the examples locally rather than just read about them.
Topics include indexes, transactions, JSONB, window functions, row-level security, vacuum, locks, and replication. Content is read through a CLI (pgbook read locks), and no signup is required. It suits developers who want depth on specific features without reading a book end to end.
