PostgreSQL includes extensive documentation, including a large manual, manual pages, and some test examples. See the /doc directory. You can also browse the manuals online at http://www.PostgreSQL.org/docs. There are two PostgreSQL books available online at http://www.postgresql.org/docs/books/awbook.html and http://www.commandprompt.com/ppbook/. There are a number of PostgreSQL books available for purchase. One of the most popular ones is by Korry Douglas. A list of book reviews can be found at http://techdocs.PostgreSQL.org/techdocs/bookreviews.php. There is also a collection of PostgreSQL technical articles at http://techdocs.PostgreSQL.org/. The command line client program psql has some \d commands to show information about types, operators, functions, aggregates, etc. – use \? to display the available commands. Our web site contains even more documentation.
