Production-Ready PostgreSQL: Designing, Optimizing, and Operating Reliable Database Systems (Paperback) (ISBN-13: 9798180817617)

Build PostgreSQL systems that survive the realities of production.

Most PostgreSQL books teach features.

This book teaches engineering judgment.

As applications grow, the challenges change. Queries that once completed instantly begin slowing down. Migrations become riskier. Connection pools saturate. Replication lag appears unexpectedly. Background workloads compete with customer-facing traffic. Small operational shortcuts accumulate into costly incidents.

Production-Ready PostgreSQL is a comprehensive guide for software engineers, database administrators, site reliability engineers, and technical leaders who want to design and operate PostgreSQL systems with confidence.

Rather than focusing solely on syntax or isolated features, this book explores how PostgreSQL behaves in real-world environments-and how experienced teams respond when systems are placed under pressure.

In this book, you'll learn how to:

• Plan and execute zero- or low-downtime database migrations
• Diagnose why fast queries become slow as workloads evolve
• Design indexing strategies that improve performance at scale
• Understand transactions, isolation levels, locking, and concurrency behavior
• Avoid common operational mistakes that lead to production incidents
• Implement effective backup, recovery, and high-availability practices
• Monitor PostgreSQL using meaningful operational metrics
• Scale PostgreSQL responsibly without introducing unnecessary complexity
• Operate multi-tenant SaaS platforms efficiently and fairly
• Survive high-demand events through practical case studies inspired by real production challenges

Who this book is for:

* Software Engineers building data-intensive applications

* Backend Developers responsible for production systems

* Database Administrators seeking a modern operational perspective

* DevOps and Site Reliability Engineers supporting PostgreSQL environments

* Technical Leads making architectural decisions around scalability and reliability

Whether you're supporting your first production database or refining the practices of an experienced engineering team, this book provides the technical depth and practical insights needed to operate PostgreSQL with confidence.

Because databases don't earn trust by working only under ideal conditions.

They earn trust by continuing to perform when the stakes are highest.
