PostgreSQL 10 Administration Cookbook - Fourth Edition

By: Simon Riggs, Gianni Ciolli

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.

This recipe assumes that you have read the previous recipe, Hot physical backups with Barman, and successfully installed Barman on the malcolm server, backing up the Postgres databases running on angus and bon. We will use the same nomenclature in the examples in this recipe.

A recovery procedure is a reaction to a failure. In database terms, this could be related to an unintentional human error (for example, a DROP operation on a table), an attack (think of Little Bobby Tables), a hardware failure (for example, a broken hard drive), or (less likely) a natural disaster.

Even though you might be tempted to think that you are immune to disasters or failures (we wish you were), you are advised to perform regular tests and simulations of recovery procedures. If you have a team of engineers, we suggest that you schedule a simulation every six months (at least)...
