PostgreSQL Mastery: Schema Design, Query Tuning, and HA (English Edition) pdf

PostgreSQL Mastery: Schema Design, Query Tuning, and High Availability is the definitive guide for developers, DBAs, and data engineers who want to build fast, reliable, and scalable PostgreSQL systems in the real world.

This book goes beyond basic SQL and theory. You’ll learn how PostgreSQL actually behaves under load—and how to design, tune, and operate databases that perform flawlessly in demanding production environments.

Starting with rock-solid schema design, you’ll discover how to model data for long-term flexibility, enforce integrity without sacrificing speed, and avoid costly redesigns as your system grows. From there, you’ll dive deep into query tuning, mastering indexes, execution plans, and performance diagnostics so you can confidently optimize even the most complex workloads.

Finally, the book tackles high availability and resilience, showing you how to keep PostgreSQL online when it matters most. You’ll explore replication strategies, failover design, backups, and operational best practices that power mission-critical systems.

Whether you’re maintaining a growing SaaS platform, optimizing analytics workloads, or preparing PostgreSQL for enterprise-scale traffic, this book gives you the tools and mindset of an expert.

Inside, you’ll learn how to:

• Design schemas that scale without becoming fragile

• Diagnose and fix slow queries using PostgreSQL’s planner and statistics

• Choose and tune indexes for real performance gains

• Prevent bottlenecks before they reach production

• Implement replication, backups, and high-availability architectures

• Operate PostgreSQL with confidence under heavy load

Clear, practical, and battle-tested, PostgreSQL Mastery is the guide you’ll keep coming back to as your systems—and your expertise—grow.
