True. The idea there is that we can turn frequent update on/off fairly
easily for normal tables since there are no tuple format changes in the
main heap. It also allows HOT to avoid wasting space when a table is
heavily updated in certain places only.
I general though, it would make implementation a bit simpler when tuples with
different header are isolated in a different relation.
