PostgreSQL 18 for Developers: Build High-Performance Databases with SQL, Database Design, Query Optimization, JSONB, Security, Docker, Cloud Deployment, and Hands-On Projects

Still using PostgreSQL like a simple database when it can do so much more?
PostgreSQL 18 for Developers is a practical, hands-on guide designed to help you build modern, reliable, and high-performance database applications with the latest features of PostgreSQL 18. If you know SQL basics but want to design better databases, write faster queries, and create production-ready applications, this book gives you the skills to do it with confidence.
Many developers can create tables and run simple queries, but struggle when projects become larger and more demanding. This book bridges that gap by showing you how to design efficient schemas, optimize performance, secure your data, and use PostgreSQL’s advanced capabilities in real-world development.

Inside, you’ll learn how to:

• Build well-structured databases using modern PostgreSQL 18 best practices
• Design schemas, relationships, constraints, and indexes that scale
• Write efficient SQL queries, joins, subqueries, window functions, and Common Table Expressions (CTEs)
• Use PostgreSQL 18 features, including UUIDv7 support, generated columns, JSON, arrays, and advanced data types
• Optimize query performance with EXPLAIN, indexing strategies, and query tuning
• Implement transactions, concurrency control, backups, replication, and high availability
• Secure your databases with roles, permissions, authentication, and encryption
• Connect PostgreSQL to Python, Java, Node.js, and modern web applications
• Build a complete production-ready application while applying professional database development practices

By the end of this book, you’ll know how to design robust databases, write efficient SQL, troubleshoot performance issues, and build scalable PostgreSQL applications that are ready for real-world deployment. Whether you’re a software developer, backend engineer, database administrator, or computer science student, you’ll gain practical skills you can immediately apply to professional projects.
