No, I wouldn't do that.  I would keep the routines you mention ignorant
of ResourceOwner, because I think that the vast majority of tupdesc
usage will NOT be using ResourceOwners.  Only the places where a pointer
to a cached tupdesc is handed out need to deal with this.  This excludes
practically all of the executor, for instance.

If you're finding yourself writing a large and invasive patch, I think
you're doing it wrong.  I'm envisioning something pretty localized.
