Start psql with -E option to see the statements used internally.

From the psql man-page :
-E

--echo-hidden
       Echoes the actual queries generated by \d  and  other  backslash
       commands.  You can use this if you wish to include similar func-
       tionality into your own programs. This is equivalent to  setting
       the variable ECHO_HIDDEN from within psql.

If this is not _exactly_ what you need, then you're not exactly
explaining what you're trying to do :)
