In this chapter, we have learned how to systematically approach a database system and detect the most common issues that people face with PostgreSQL. We learned about some important system tables, as well as some other important factors that can determine whether we 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 want to check out PostgreSQL. In Chapter 13, Migrating to PostgreSQL, we'll discuss everything that is involved with this.
