Summary

In this chapter, you learned about basic replication-related concepts as well as the physical limitations. We dealt with the theoretical concepts, which are the groundwork for what is still to come in this book.

In the next chapter, you will be guided through the PostgreSQL transaction log, and we will outline all important aspects of this vital component. You will learn what the transaction log is good for and how it can be applied.
