I was able to get this working pretty quickly. All regression tests
pass. I'm not going to post a patch just yet, because I still need to
make the cluster case work, and I'll probably want to refactor my
approach to performing catalog lookups a bit, but the important point
is that my original suspicion that this isn't very difficult or
invasive has been confirmed.
I should have something to post before too long.
