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.

Collect regular statistics from pg_stat* views

This recipe describes how to collect the statistics needed to understand what is going on in the database system on a regular basis so that they can be used to further optimize the queries that are slow or are becoming slow as the database changes.

We have included an example extension, called pgstatslog. It can be used to track these changes. The extension works on PostgreSQL 9.1+.

Look at the Using an installed module and managing installed extensions recipes from Chapter 3, Configuration, for an overview of the extensions infrastructure in PostgreSQL.
