Hey folks, I just spoke with our director of netops Tom Sparks here at
Norse and we have a vested interest in Postgresql. We can throw
together a cluster of 4 machines with specs approximately in the range
of dual quad core westmere with ~64GB of ram running FreeBSD 10 or 11.
We can also do an Ubungu install as well or other Linux distro. Please
let me know if that this would be a something that the project could
make use of please.

We also have colo space and power, etc. So this would be the whole
deal. The cluster would be up for as long as needed.

Are the machine specs sufficient? Any other things we should look for?

CC'd Tom on this email.

-Alfred
