In this chapter, you learned to systematically approach a database system and detect the most common issues people face with PostgreSQL. You learned about some important system tables, as well as some other important factors that can determine whether you will succeed or fail.
In the final chapter of this book, we will focus our attention on migrating to PostgreSQL. If you are using Oracle or some other database system, you might be willing to check out PostgreSQL. Chapter 13, Migrating to PostgreSQL, will tell you how to do that.
