I wonder whether at some point we shouldn't just eliminate this distinction
entirely. Just make "text" and "varchar" the same type and spell it "text"
when there's no typmod length restriction and "varchar(x)" when there is.

That's particularly scary because it means that databases which load piles of
contrib modules have that much more of an effect here. Some contrib modules
create a *lot* of operators.
