Depending on what information you're looking for, you might need to query any of the following tables: pg_attrdef pg_attribute pg_class pg_constraint pg_depend pg_index See also "Miscellaneous Functions" ("System Information Functions" in 8.x) in the "Functions and Operators" chapter of the documentation. It can also be useful to run "psql -E" or use "\set ECHO_HIDDEN" in psql to show the SQL queries that psql makes for \d commands. -- Michael Fuhr
