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 PostgreSQL 16 is the expanded SQL/JSON syntax, which gives developers more control over JSON data management. Additionally, the book teaches new monitoring capabilities introduced with the pgstatio 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, loadbalancehosts, which distributes traffic efficiently among multiple servers. The goal of this book is to provide you with the knowledge you need to successfully manage, optimize, and troubleshoot database environments by providing a deep-dive understanding of how to implement and benefit from PostgreSQL 16's latest features. Key LearningsBoost data availability and workload distribution using advanced logical replication techniques. Apply the SIMD acceleration to expedite the processing of ASCII and JSON strings. Make use of improved SQL/JSON syntax to manage complicated JSON data operations. Utilize pgstatio for troubleshooting and monitoring I/O operations. Utilize Rust libraries like pgx and rust-postgres for easy integration with PostgreSQL. Distribute workload among numerous PostgreSQL instances by configuring loadbalancehosts.
