Logical Replication

In the previous chapter, we talked about WAL segments and physical replication in synchronous, asynchronous, and cascading modes. In this chapter, we will cover the topic of logical replication. We will look at how to perform a logical replica, how a logical replication is different from a physical replication, and when it's better to use logical replication instead of physical replication. We'll also see that logical replication can be used to make a PostgreSQL hot upgrade. This chapter is intended to be just an introduction to logical replication; for further information, refer to more advanced texts, such as Mastering PostgreSQL 12, Hans-Jürgen Schönig, Packt Publishing.

This chapter covers the following topics:

  • Understanding basic concepts
  • Exploring logical replication setup
