Absolutely, and I said in
but applied to the Postgres B-tree indexes instead of heaps. It's a pretty
obvious performance improvement really - the principle is that when you do
have to fetch a page from a slower medium, you may as well make it count
for a lot.
Lots of research has already been done on this - the paper linked above is
rather behind the times.
However, AFAIK, Postgres has not implemented this in any of its indexing
An ant doesn't have a lot of processing power available to it. I'm not trying
to be speciesist - I wouldn't want to detract you from such a wonderful
creature, but, well, there isn't a lot there, is there?
