I take it that you are looking to create stored procedures? In postgresql they are called "stored functions" or more correctly "functions."
First you will need to load a procedural language into your database if one isn't already installed.
http://www.postgresql.org/docs/8.2/interactive/sql-createlanguage.html
You should probably use PLpgSQL since it is available across OS all platforms and is easy to learn and use.
http://www.postgresql.org/docs/8.2/interactive/plpgsql.html
There are some nice examples in this documentation.
Your PGadmin will also have features to help the create these functions also.
