The particular regression tests we have for those functions seem to pass
constants to them, not table columns, and so they don't see packed inputs.

(It might be interesting to make textin produce a packed result when
possible, just to see what breaks; but I would be afraid to try to do
that for production...)

I'm very much against such a wholesale edit as you seem to have in mind
here.  We already had some destabilization from the limited patch that
went in; now when we're trying to get to beta is not the time for more.
Maybe at the beginning of 8.4 devel cycle would be a reasonable time
to consider touching a lot of files.
