Your problem doesn't necessarily have anything to do with disk space;
the kernel tends to use that same error code for all sorts of
out-of-resources problems. If you were starting or stopping a
postmaster then I'd think the problem is probably insufficient
kernel settings for semaphores or shared memory. See
