Thinking in PostgreSQL: Mental Models for Senior Engineers

Thinking in PostgreSQL explores how senior engineers reason about PostgreSQL as a long-lived data system rather than a query engine. The book focuses on mental models, architectural tradeoffs, and operational thinking behind transactions, MVCC, schema evolution, performance, reliability, and failure. It emphasizes judgment, responsibility, and long-term decision-making over syntax or tuning recipes, helping experienced engineers design PostgreSQL systems that remain correct, maintainable, and trustworthy as they grow.
