It isn't. As Hannu showed these features should live in harmony (if we
will accept Oracle's syntax). I see as real problem new column in
pg_proc, that allow quickly chose between labeled and non labeled
functions - and then collect labels in parse time. This is way for
adding parameter info into variadic function - it's main goal of this
proposal. Without column in pg_proc it could same slowdowns like first
variadic function's implementation.
