Summary

In this chapter, we learned about some of the most promising modules that are shipped with the PostgreSQL standard distribution. These modules are pretty diverse and offer everything from database connectivity to case-insensitive text and modules so that we can inspect the server. However, in this section, you have learned about the most important modules around. This will help you to deploy even greater database setups.

Now that we have dealt with extensions, in the next chapter, we will shift our attention to migration. There, we will learn how we can move to PostgreSQL most simplistically.
