You're perfectly right. I'm used to have several clusters on the same
host (application testing in my case).
In this benchmark context, though, I just was being wary that they may
interfere, For instance, I suppose that an autovacuum wakeup in one
should lower performance results of the other.
Sorry it that sounded more general than that.
