RHCS+PostgreSQL can also be used when you shard your data to multiple
databases, and use each server as "active" server, like I told in the
25th slide of the presentation that I just in the previous email.

So, RHCS and SR/HS are not competitive to each other. We have installed
them in parallel several times, like to 3 servers.
