PostgreSQL 18.6 in Practice

PostgreSQL 18.6 in Practice

Latest Security Enhancements, Query Optimization Improvements, Indexing Fixes, Replication Reliability, Backup and Recovery Updates, and Advanced Database Administration Techniques

By Johnie P. Battaglia

Are you ready to strengthen your PostgreSQL skills and learn how to manage modern database systems more efficiently? Do you want to optimize SQL queries, improve database security, manage replication, and handle unexpected database failures with confidence?

PostgreSQL 18.6 in Practice by Johnie P. Battaglia provides a practical guide to understanding, developing, securing, optimizing, and administering PostgreSQL 18.6. Whether you are a database administrator, software developer, backend engineer, or database professional, this book helps you build the knowledge needed to manage reliable database environments.

How do you identify slow queries? What causes transaction conflicts and database bottlenecks? How can you improve storage efficiency while maintaining consistent performance as workloads increase? This book explores these questions through practical explanations of PostgreSQL architecture, advanced SQL development, query planning, execution strategies, indexing, partitioning, and database maintenance.

Learn how to identify performance problems, understand execution plans, and make informed improvements to your database workloads.

Security and reliability are equally important. Explore authentication, role management, encryption considerations, access control, and secure database configuration. Understand how physical streaming replication and logical replication work, how to monitor replication lag, and how standby servers support high availability and failover planning.

What happens when a database server fails or important data is accidentally modified? Can you restore your system to a specific point before the incident? This book examines backup strategies, write-ahead logging, point-in-time recovery, WAL management, and disaster-recovery procedures to help you prepare for unexpected situations.

Inside this book, you will learn how to:

• Understand PostgreSQL 18.6 architecture, configuration, and database fundamentals.

• Develop advanced SQL queries and improve query execution performance.

• Apply indexing, partitioning, vacuum, and storage-maintenance techniques.

• Strengthen database security through authentication and access control.

• Manage transactions, concurrency, locking, and isolation levels.

• Configure physical and logical replication.

• Monitor replication lag and improve database availability.

• Implement backup, recovery, and disaster-recovery strategies.

• Monitor database activity and troubleshoot performance problems.

• Understand asynchronous I/O and resource optimization.

• Manage production databases more efficiently and reliably.

Whether you are advancing your database career, managing business applications, or improving your technical expertise, this book provides practical knowledge you can apply to real PostgreSQL environments.

Don't let slow queries, security weaknesses, replication problems, or unexpected failures compromise your database operations.
