I fail to see how it'd be a dependency. I'd expect it to look up the
type when you run the command, just like plpgsql does. I think it'd be
useful to have.
That said, I think that should be a completely separate patch and
discussion. Lets at least get it into plpgsql first.
As for the array of element/element of array feature; I agree it would
be nice, but we're pretty late in the game for that, and I don't see why
that couldn't be added later.
