If I understand well to request to remove "minimal_error_message" we
need to have fault tolerant regprocedure.

I am looking on this code now, and it is not easy as I though - there
are two possible errors: not found or found more - so returning
InvalidOid is not enough - and then some "new lookup" function is not
simple or is ugly - and I am not sure, so cost is less than benefit.
in this case.
