I am playing with this now and two versions of proargtypes is 30% more
ugly code - mostly pg_dump and paradoxically  remove function -
because currently RemoveFuncStatement lost argmode, so I am missing
info about variadic parameter and I can't simply transformation from
element to array. I thing, it isn't good way.
