That's true, but my proposal to do things that way reflects the fact
that text is a type oddly tied to the platform. I don't think it will
come up again (note that in the 4 byte Datum case, we still use sort
support to some degree on other platforms with patch 2 applied). It
seemed logical to impose the obligation to deal with that on
varlena.c.
