Sounds like you need to increase your shared memory limits.
Unfortunately this will require a reboot on FreeBSD :(


Last time I checked PostgreSQL should be complaining about the shared
memory on startup rather than silently fail though. Check your logs
perhaps. Though I believe the RC script will cause the message to be
printed interactively at the console too, if you run it. (Assuming you
are using it installed from ports).
