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 file-based replication – deprecated

This technique is mostly superseded by streaming replication (PSR), so if you are a novice, you probably do not want this recipe yet. Nonetheless, this is relevant and useful as part of a comprehensive backup strategy. It is also worth understanding how this works, as this technique can also be used as the starting phase for a large streaming replication setup. Look at the following recipes for some further details on that.

Log shipping is a replication technique used by many database management systems. The master records database changes in its transaction log, and then the log files are shipped from the master to the standby, where the log is replayed.

File-based log shipping has been available for PostgreSQL for many years now. It is simple, has very low overhead, and is a trustworthy form of replication.
