The PostgreSQL performance tuning page says this:

"You might also want to configure your kernel to lock shared memory into
RAM and prevent it from being paged out to swap. Use the sysctl setting
kern.ipc.shm_use_phys."

This value doesn't appear in NetBSD and I can't find anything that looks
like it does the same thing.  Does NetBSD have some sort of control for
locking shared memory (SYSV) into RAM?
