Ah, I understand better now. hm. high data density would be good for reading.
But I think the case for inserting is actually quite mixed. If you have lots
of processes trying to insert you'll actually get poorer performance because
they'll all have to get access to the same page. Worse, you'll probably have a
unique index.

I think that actually is quite a nice effect. Certainly the loss of it is one
of the big practical disadvantages of using UUIDs over a sequence.
