I would also note that the OOM killer logs its evil deeds: printk(KERN_ERR "Out of Memory: Killed process %d (%s).\n", p->pid, p->comm); So there's no need to wonder whether that's a source of trouble for your PostgreSQL processes or not; just check the logs. I've had the OOM killer go after large Perl processes and X, but never (yet) PostgreSQL, I'm happy to say.
