semget deals with shared memory, not file systems...under FreeBSD,
you do:

%ipcs
Message Queues:
T ID KEY MODE OWNER GROUP

Shared Memory:
T ID KEY MODE OWNER GROUP
m 131072 2063597841 --rw-rw-rw- scrappy staff

Semaphores:
T ID KEY MODE OWNER GROUP

To see what is being used. ipcrm to remove 'stale'
handles...sounds like your system isn't releasing when you kill of
postgres daemon...
