Just curious if this would apply to PostgreSQL: http://queue.acm.org/detail.cfm?id=1814327
Absolutely, and I said in http://archives.postgresql.org/pgsql-performance/2010-03/msg00272.php 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 systems.
