Practical PostgreSQL

This book is a practical guide to PostgreSQL for engineers. It focuses on the essentials you need to build, evolve, and operate production databases with confidence.

What you’ll find inside:
- Fundamentals: schemas, types, constraints, indexes, functions, and triggers
- Safe changes: migrations, column/table/type changes, constraints, and user/role management
- Proven patterns: status modeling, soft deletes, pagination, rollups, compaction, advisory locks, and more
- Debugging: sizing, slow queries, diagnostic helpers
- Application recipes: dynamic filtering/sorting, upserts, JSONB workflows, bulk ingest, and maintenance

Each chapter follows a consistent structure: problem/context, implementation steps (with copy‑pasteable SQL), pitfalls, recap, and a quick “Summary (Cheat Sheet).” Examples use standard PostgreSQL syntax and are written with production safety in mind (batching, concurrent operations, validation).

Use it end‑to‑end or as a reference. Start with the basics, apply the patterns as needed, and adopt the safe‑change practices to minimize risk during deployments.
