E-Books →PostgreSQL 18 Explained A Complete Guide for Developers, DBAs, and Architects

PostgreSQL is no longer just a database-it is a strategic platform. PostgreSQL 18 marks a turning point in how modern systems are built, scaled, and operated, and this book shows you exactly how to stay ahead of that shift.
This book is a practical, in-depth guide to PostgreSQL 18, written for engineers, architects, and technical leaders who need to understand not only what has changed, but why it matters in production. You will learn how PostgreSQL 18 works internally, how its new execution, storage, indexing, security, and replication capabilities affect real workloads, and how to design systems that remain fast, reliable, and maintainable over the long term. Rather than listing features, the book connects PostgreSQL internals to real operational decisions you face every day.
By reading this book, you will gain the ability to reason confidently about performance, capacity, and reliability. You will understand how the query planner really makes decisions, how asynchronous I/O and parallel execution change workload behavior, how to choose the right indexing and schema strategies, and how to operate PostgreSQL safely in production environments-from backups and upgrades to monitoring, incident response, and high availability design. The result is fewer surprises, faster systems, and stronger architectural decisions.
What sets this book apart is its focus on production reality. It bridges theory and practice by explaining PostgreSQL internals in clear language while grounding every concept in real-world use cases, trade-offs, and operational consequences. It does not assume blind trust in defaults or folklore-it teaches you how PostgreSQL actually behaves, so you can make informed decisions as systems grow and evolve.
If you are responsible for building, scaling, or operating PostgreSQL systems-and you want to fully understand PostgreSQL 18 rather than simply use it-this book is your definitive guide.
