Summary

In this chapter, you've seen that PL/pgSQL provides a way for you to execute procedural code on the server. PL/pgSQL is not the only procedural language that you can use for server-side programming. The standard PostgreSQL distribution includes PL/perl, PL/python, and PL/tcl. You can also add functionality to the server using the Server Programming Interface. For more information on these features, refer to the PostgreSQL Programmer's Guide .

The next several chapters will describe the client-side programming interfaces included with PostgreSQL.
