Can we? I mean, sure you can break the patch up into chunks which might make
it easier to read, but are any of the chunks useful alone?
I suppose inserting HOT tuples without index maintenance is useful even if no
changes to the space allocation is made is useful. It won't get the space
usage but it would save on index thrashing. But that still implies all the
code to handle scans, updates, index builds, etc. Those chunks could be
separated out but you can't commit without them.
