Overview of this book

PostgreSQL is an open source database used for handling large datasets (Big Data) and as a JSON document database. It also has applications in the software and web domains. This book will enable you to build better PostgreSQL applications and administer databases more efficiently. We begin by explaining the advanced database design concepts in PostgreSQL 9.6, along with indexing and query optimization. You will also see how to work with event triggers and perform concurrent transactions and table partitioning, along with exploring SQL and server tuning. We will walk you through implementing advanced administrative tasks such as server maintenance and monitoring, replication, recovery and high availability, and much more. You will understand the common and not-so-common troubleshooting problems and how you can overcome them. By the end of this book, you will have an expert-level command of the advanced database functionalities and will be able to implement advanced administrative tasks with PostgreSQL.

Handling Backup and Recovery

In the previous chapter of this book, I tried to teach you all you need to know about securing PostgreSQL in the most simplistic and most beneficial way possible. The topics of this chapter will be backup and recovery. Performing backups should be a regular task and every administrator is supposed to keep an eye on this vital stuff. Fortunately, PostgreSQL provides easy means to create backups.

The following topics will be covered:

  • Running pg_dump
  • Partially dumping data
  • Restoring backups
  • Making use of parallelism
  • Saving global data

At the end of the chapter, you will be able to set up proper backup mechanisms.
