Overview of this book

This second edition of Mastering PostgreSQL 11 helps you build dynamic database solutions for enterprise applications using the latest release of PostgreSQL, which enables database analysts to design both the physical and technical aspects of the system architecture with ease. This book begins with an introduction to the newly released features in PostgreSQL 11 to help you build efficient and fault-tolerant PostgreSQL applications. You’ll examine all of the advanced aspects of PostgreSQL in detail, including logical replication, database clusters, performance tuning, monitoring, and user management. You will also work with the PostgreSQL optimizer, configuring PostgreSQL for high speed, and see how to move from Oracle to PostgreSQL. As you progress through the chapters, you will cover transactions, locking, indexes, and optimizing queries to improve performance. Additionally, you’ll learn to manage network security and explore backups and replications, while understanding the useful extensions of PostgreSQL so that you can optimize the speed and performance of large databases. By the end of this book, you will be able to use your database to its utmost capacity by implementing advanced administrative tasks with ease.

PostgreSQL Overview

Making Sense of Backups and Replication

In Chapter 9, Handling Backup and Recovery, we learned a lot about backup and recovery, which is essential for administration. So far, only logical backups have been covered; I am about to change that in this chapter.

This chapter is all about PostgreSQL's transaction log and what we can do with it to improve our setup and to make things more secure.

In this chapter, we will cover the following topics:

  • What the transaction log does and why it is needed
  • Performing point-in-time recovery
  • Setting up streaming replication
  • Replication conflicts
  • Monitoring replication
  • Synchronous versus asynchronous replication
  • Understanding timelines
  • Logical replication
  • Creating subscriptions and publications

By the end of this chapter, you will be able to set up transaction log archiving and replication. Keep in mind that this chapter can never be a comprehensive...
