PG under OpenVZ?

Hi!

I've found an old thread on OpenVZ:

(2008): http://archives.postgresql.org/pgsql-performance/2008-03/msg00076.php

And a more recent question that scared me a bit:

(2011): http://serverfault.com/questions/281783/running-mongodb-with-openvz

On the PostgreSQL general mailing list, I've only found 54 results when searching for OpenVZ. I'm wondering if OpenVZ is simply unpopular, or not used at all for PG. What experiences do you have with OpenVZ? Any performance problems?

We're buying bare metal to run our clusters on, and the supplier is late delivering the machines. They suggested lending us a machine and run PostgreSQL under OpenVZ. When the real hardware is ready, we'd migrate the VZ over to the new physical servers. Thoughts on this?

I have no experience with OpenVZ itself, so if you have general comments about it's stability and/or performance, even unrelated to PostgreSQL, I'd appreciate.

Thanks!
François
