A comprehensive review of Denis Magda's book covering PostgreSQL's capabilities beyond traditional relational features. The 402-page guide explores core database concepts like indexing (B+Tree, hash, partial), transactions, and modern SQL features (CTEs, window functions), then dives into non-relational capabilities including JSON storage and full-text search. The book examines PostgreSQL's extension ecosystem: pgvector for ML/GenAI embeddings, TimescaleDB for time series data, PostGIS for geospatial queries, and pgmq for message queues. Includes performance tuning guidance and discusses when PostgreSQL might not be the right choice.
