See these two chapters in the postgresql docs: http://www.postgresql.org/docs/8.1/interactive/catalogs.html http://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. Sean
