I've had trouble getting programs that use shared memory (such as Postgres)

Postgres needs this in the host rc.conf:
jail_sysvipc_allow="YES"
My experiments with Postgres in jail predate the existence of that setting.
When I was working with it, you had to frob a sysctl via /etc/sysctl.conf
But even then, I couldn't seem to get it to work -- the Postgres in the
jail would corrupt the shared memory of the postgres outside the jail.
It was ugly. Imagine big, wet tears rolling down my cheeks.
I haven't had the need to try it in a while, so it might work OK now, I
just don't know.
Ah, now that you mention it I do recall discussions of multiple
instances peeing in each others pools so to speak. I also thought
there was discussion of how to fix it, but have no idea where that
went if anywhere...
A single instance inside a jail does work quite happily if the knob
above is set.
