Victor - Don't know why I was thinking in terms of DELETE, but yeah, the point is the same.
If the fields being updated don't have stats, the comparison would be "update in place" versus "insert to empty table + collect stats + make
grants ," not just "update in place" versus "insert to empty table + make grants." (Leaving aside other issues like availability during the
update, space limits, etc.)
