Unfortunately I can't do that (well, in fact it would be pretty
inconvenient) because the function is called from other plpgsql function
and I cannot be sure if it will be called with NULL or not. Anyway I
seem to resolved the problem by writing another doing-nothing-at-all
function with the same name and "unknown' argument type.
