Hmm...it worked fine for me in -CURRENT a little while ago with a
generic kernel.  I sometimes tweak the postgresql source to change
the value of IPC_NMAXSEM, but I'm pretty sure I didn't this time.
In any case, postgresql's default is to use 32 semaphores, and
src/sys/kern/sysv_sem.c suggests that the FreeBSD default is to
support up to 60, so I'm not sure why you needed a custom kernel.
