The hardware is perfectly fine. Are you going to host oracle
as well? I think we want 4 instances: stable and head for pg and oracle but they won't get a lot of traffic so mostly it's just a matter of having enough memory to run pg, oracle, and 4
servers on one box without it falling over.
I think it would be hard to attribute regression failures to individual committers but something like a daily or weekly summary people could subscribe to might be useful. I think that should be a job for the test server which aggregates test results and not for the test instances themselves.
