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.

Setting up streaming replication

Log shipping is a replication technique used by many database management systems. The master records change in its transaction log (WAL), and then the log data is shipped from the master to the standby, where the log is replayed.

In PostgreSQL, PSR transfers WAL data directly from the master to the standby, giving us integrated security and reduced replication delay.

There are two main ways to set up streaming replication: with or without an additional archive. Setting it up without an external archive is presented here, as it is the more simple and efficient way. However, there is one downside that suggests that the simple approach may not be appropriate for larger databases, which is explained later in the recipe.
