Summary

In this chapter, we 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. It is especially important to keep an eye on table bloat and dangerous error messages. Note that depending on the type of workload, you might face different challenges. The most important ones have been covered in this chapter.

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 involved in this.
