You are right that patch is not in committable shape, but the patch to
move the map to relcache is presented and the main work left there is
to review/test and add the invalidation calls as per discussion. It
is just that I don't want to that in haste leading to some other
problems. So, that patch should not take too much time and will
resolve the main complaint. Basically, I was planning to re-post that
patch as the discussion concludes between me and Alvaro and then
probably you can also look into it once to see if that addresses the
main complaint. There are a few other points for which John has
prepared a patch and that might need some work based on your inputs.

I can certainly help with moving patch (for cleanup) forward.
