BTW: That would have the nice side-effect of delivering the basis of what you need to do parallel sort in a transaction that previously has performed DDL. Currently you cannot do anything in parallel after DDL, even if you only scan the table in one backend, because operators et al. have to do catalog lookups which you can't do consistently since cmin/cmax aren't available in both.
