This chapter has given you a gentle introduction to PostgreSQL. You have seen how to install PostgreSQL on your system and how to configure it for use. You've also created a sample database that you'll use throughout the rest of this book.
In the next chapter, I'll discuss the many PostgreSQL data types in more depth, and I'll give you some guidelines for choosing between them.
