I don't think Simon's proposal is meant to address that issue, but did
you follow the thread I started in September about Block B-Tree index:
http://archives.postgresql.org/pgsql-hackers/2006-09/msg02041.php

That's our plan to achieve speedups that other DBMS's have achieved with
Index-Organized-Tables or Clustered Indexes. We're running initial
performance tests of it as we speak, and if all goes well we're hoping
to get that into PostgreSQL 8.3.
