The traditional manual way to do the latter is
begin;
drop <object>;
... read the error message about what the drop would cascade to ...
rollback;
If you feel like getting down-and-dirty with the implementation you
could troll the contents of pg_depend for yourself. I think it would
be kind of painful to do without writing some C code though, because
a lot of useful operations like getObjectDescription() aren't exposed
at the SQL level.
