That's why he said vacuum when done. Anyway, I'm not sure that a big
*contiguous* hole in the middle of the table would matter as much for
queries, because most rows would still be close to each other--most
queries
would pull from one side or other of the hole, and even for those that
didn't, it would be one seek across the hole, not seeking all over the
place?
