PostgreSQL 18 Optimization in Practice

For developers, data engineers, and PostgreSQL users working with real-world systems.

Your PostgreSQL queries work... but they don't scale.

Slow dashboards.
High CPU usage.
Unpredictable query performance.
And no clear idea why it's happening.

If you've ever written a query that works perfectly on small data-but collapses in production-you're not alone. Most developers learn SQL, but never truly learn PostgreSQL performance tuning or how the engine behaves under load.

You've been taught how to write queries.
But not how to optimize PostgreSQL databases in real systems.

So you're stuck:

• Guessing why queries are slow
• Applying SQL query optimization techniques without clear results
• Adding indexes without a solid PostgreSQL indexing guide
• Fighting performance issues without a repeatable system

PostgreSQL 18 Optimization in Practice is a complete, hands-on guide to PostgreSQL query optimization and real-world database performance tuning.

You won't just learn what to do-you'll learn how to think like the PostgreSQL engine and apply high performance SQL strategies that actually scale.

Whether you're working in backend systems or exploring data engineering with PostgreSQL, this book gives you the tools to take full control of performance.

• Fix slow queries using EXPLAIN ANALYZE like an expert
• Apply proven PostgreSQL performance tuning techniques
• Design indexing strategies with a practical PostgreSQL indexing guide
• Optimize JOINs, filtering, and aggregation for large datasets
• Identify real bottlenecks (CPU, I/O, memory, and concurrency)
• Build scalable systems with backend performance optimization principles
• Master query execution plans and PostgreSQL internals
• Apply database performance tuning in real production scenarios

Plus, you'll follow a real-world e-commerce database system, so you can see exactly how to optimize PostgreSQL databases step by step.

• Are learning or working with PostgreSQL for developers
• Want to move from writing queries → engineering performance
• Are interested in backend systems or data engineering with PostgreSQL
• Need practical, real-world SQL query optimization techniques
• Want to confidently build and scale high-performance systems
