I'm sure those wiser than me will chime in with specifics. I think
you should be think of usage not in terms of number of databases but
in terms of connections rates, database size (numbers of tables and
tuples) and the types of queries that will be run. While there may be
a little overhead in from having a number of databases in the
cluster, I think this is probably going to be insignificant in
comparison to these other factors. A better idea of what the usage
will guide you in choosing your hardware.
