You can't do this safely.  PostgreSQL wants to control its disk.
Someone has said on the (?) -general list that he has modified the
PostgreSQL code to do this, but it makes me nervous.

The Postgres-R project is trying to do something similar, but it's
some way from production quality.

I sort of wonder why "no replication" is a requirement.  If you want
lots of cheap, read-only machines, why not do it with replication?
You can buy a _lot_ of x86 boxes with Promise IDE RAID and big, fast
IDE drives for the price of ORAC.
