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.
