PostgreSQL 16 Cookbook, 2nd Edition: Solve challenges across scalability, performance optimization, essential commands, cloud provisioning, backup, and recovery

Offering a detailed practical look at PostgreSQL 16’s new features, “PostgreSQL 16 Cookbook, Second Edition” equips database administrators and developers to take advantage of the most recent developments. This edition provides in-depth coverage of enhanced logical replication, which now includes the ability to replicate from standby servers. We provide detailed instructions for setting up these advanced replication configurations, allowing you to better distribute workloads and improve data availability. The optimization of concurrent bulk loading capabilities for faster data ingestion is another noteworthy addition. Another standout feature of our book are the practical solutions and examples for using the new JSON functions and operators to store, query, and manipulate JSON data in your applications.

We walk you through the process of configuring refined user roles and permissions, ensuring effective access control in complex environments. Additionally, the book teaches new monitoring capabilities introduced with the pg_stat_io view, which provide insights into I/O operations to help optimize performance. The book goes on to implement performance enhancements such as SIMD acceleration for processing ASCII and JSON strings, as well as the new load balancing feature, load_balance_hosts, which distributes traffic efficiently among multiple servers. The goal of this book is to equip you with to successfully manage, optimize, and troubleshoot database environments.
