Overview of this book

PostgreSQL is a powerful, open source database management system with an enviable reputation for high performance and stability. With many new features in its arsenal, PostgreSQL 10 allows users to scale up their PostgreSQL infrastructure. This book takes a step-by-step, recipe-based approach to effective PostgreSQL administration. Throughout this book, you will be introduced to these new features such as logical replication, native table partitioning, additional query parallelism, and much more. You will learn how to tackle a variety of problems that are basically the pain points for any database administrator - from creating tables to managing views, from improving performance to securing your database. More importantly, the book pays special attention to topics such as monitoring roles, backup, and recovery of your PostgreSQL 10 database, ensuring high availability, concurrency, and replication. By the end of this book, you will know everything you need to know to be the go-to PostgreSQL expert in your organization.
Table of Contents (14 chapters)


Performance and concurrency are two problems that are often tightly coupled -- when concurrency problems are encountered, performance usually degrades, in some cases a lot. If you take care of concurrency problems, you will achieve better performance.

In this chapter, we will show you how to find slow queries and also how to find queries that make other queries slow.

Performance tuning, unfortunately, is still not an exact science, so you may also encounter a performance problem not covered by any of the given methods.

We will also show you how to get help in the final recipe, Reporting performance problems, in case none of the other recipes covered here work.
