Build AI Agents That Do More Than Generate Answers—Engineer Systems That Can Be Trusted. AI agents are becoming more powerful, but connecting them to real business data introduces serious challenges: unreliable retrieval, outdated information, insecure database access, lost memory, and failed operations. POSTGRESQL FOR AI AGENTS is a practical, hands-on guide to building reliable AI-agent systems with PostgreSQL, pgvector, Python, Retrieval-Augmented Generation (RAG), persistent memory, and Model Context Protocol (MCP). Through AtlasDB, an evolving PostgreSQL-powered intelligence platform, you'll learn to design, build, secure, evaluate, and operate AI applications using real database engineering techniques. Inside this book, you'll learn how to: Build PostgreSQL-powered AI agents using Python and secure database tools. Master pgvector with semantic search, HNSW, IVFFlat, and vector indexing. Engineer RAG pipelines with hybrid retrieval, reranking, and source attribution. Implement persistent agent memory with reliable storage, retrieval, and recovery. Build MCP servers that expose controlled PostgreSQL capabilities. Secure AI-generated database operations with least-privilege access, validation, and row-level security. Coordinate multi-agent workflows using transactions, checkpoints, and durable work queues. Optimize PostgreSQL performance with query plans, indexing, connection pooling, and benchmarking. Evaluate and operate AI systems with automated tests, monitoring, backups, and recovery procedures. Every stage combines clear explanations, practical SQL and Python examples, engineering investigations, and reproducible verification exercises. All essential implementations are included in the book—no external code repository required. Who This Book Is For Python developers, PostgreSQL practitioners, AI engineers, and software architects who want to move beyond basic AI demonstrations and build dependable, database-backed applications. Go beyond connecting an LLM to a database. Learn to engineer the data, memory, security, and reliability foundations that serious AI agents require.
