FWIW, I just found myself forced to invent pg_get_function_arguments()
and pg_get_function_result(), because the TABLE function patch has
pushed the complexity of printing function argument and result types
well beyond the bounds of sanity.  (Pavel had hacked up pg_dump and
ignored psql's \df ...)  It wouldn't take a whole lot to convince me
that a pg_get_functiondef would be useful, although I don't foresee
either of those applications wanting to use it because of their
backward-compatibility constraints.
