Looks nice. You should mark the link to the perf tips at Varlena.com as
"PostgreSQL 7.4" and augment it with the current version here:

as well as the Annotated .Conf File:

For my part, I've generally seen that SATA disks still suck for read-write
applications. I generally rate 1 UltraSCSI = 2 SATA disks for anything but
a 99% read application.
