two postgres servers on one machine?
I once tried to run two (6.? series) servers on one machine.
They stepped on each others shared memory. I would like to
transition to Postgres 7 one customer (database) at a time, so
I am wondering if there is a way to run Pg 6.? and Pg 7 on the
same machine?

I do that all the time. As long as you give each server its own
data directory and its own port number, they won't conflict.
AFAIK that's always been true --- but there didn't use to be an
interlock to prevent you from trying to start two servers with
conflicting port numbers, so if you screwed up a shared-memory
clobber might well be the first symptom of the mistake.

Same version, unlike Kurt's idea above of two different versions?
I've got an application coming up that will benefit from this for sure!
