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.

Accessing multiple servers using the same host and port

We will now show you one simple, yet important, application of the previous recipe, Setting up a connection pool. In that recipe, you saw how to reuse connections with PgBouncer, and thus reduced the cost of disconnecting and reconnecting.

Here, we will demonstrate another way to use PgBouncer—one instance can connect to databases hosted by different database servers at the same time. The databases can be on separate hosts, and can even have different major versions of PostgreSQL!

Getting ready

Suppose we have three database servers, each one hosting one database. All you need to know beforehand is the connection string for each database server.
