That's interesting. ZERO % of CMD's clients have converted to 9.0 and
many have no current inclination to do so because they are already
easily served by Londiste, Slony, DRBD or Log Shipping.
I would also agree that the minority of our users will want replication.
The majority of CMD customers, PGX customers, EDB Customers will want
replication but that is by far NOT the majority of our (.Org) users.
