See these two chapters in the postgresql docs:
http://www.postgresql.org/docs/8.1/interactive/catalogs.htmlhttp://www.postgresql.org/docs/8.1/interactive/information-schema.html
Each has advantages over the other.
Also, if you start psql with the flag --echo-hidden, when you do commands like
\dt and \d+, psql will show you the sql it uses to produce that output.
