It seems there are certain projects running at the moment that will eventually make possible
to run PostgreSQL on FreeBSD's jail (virtual server on plain iron speed).
Pre jail resource limits:
http://freebsdfoundation.blogspot.com/2010/07/resource-containers-project.html
Further generalization improvements:
http://freebsdfoundation.blogspot.com/2010/06/update-on-jail-based-virtualization.html
"Further, the project includes generalization of the virtual network stack framework, factoring out common code.
This will provide an infrastructure and will ease virtualization of further subsystems like SYSV/Posix IPC with minimal overhead.
All further virtualized subsystems will immediately benefit from shared debugging facilities, an essential feature for early adopters
of the new technology."
By solving the SYSV/IPC problems, PostgreSQL will be able to be run on jails, even easier and more robustly
than it is the case now.
Lets hope those guys will deliver smth good.

We've been doing that across the project infrastructure for 10 years
or more. The only issue we run into is that we need to use a unique
port in each jail as shared memory isn't entirely isolated between
jails.

Thats a pretty known workaround, still inconvenient and annoying for massive scale
virtual environments.
