Chapter 22. Extending PostgreSQL

PostgreSQL is built on a flexible core that offers the programmer tremendous power and flexibility. Writing extensions to the database is an easy task, and many people have already implemented additional features and interfaces to the database. PostgreSQL's flexibility and its clear internal structure make the database a playground for every computer programmer who wants to work with a reliable and highly sophisticated DBMS. This chapter is dedicated to those who want to write simple extensions to the database. You will be guided through the basic concepts and see how extensions can be built. We won't go into too much detail because that would be beyond the scope of this book, but you can find more detail on this topic in PostgreSQL Developer's Handbook (Sams Publishing).
