I have one word for you: CLUSTER. Without it, index lookups are too
slow. With it, they are rapid. I have done some work like this
commerically with Ingres, which has an ISAM type that keeps the matching
rows pretty close on a newly-created ISAM index. In PostgreSQL, and
regular CLUSTER will keep you good.

If you find it slow, let me know. I have done some benchmarking with
the author and he found it pretty fast, usually a few seconds. See the
section in my book on CLUSTER for information on _why_ it helps.
