I think the behaviour is that if the system as a whole runs out of memory
(physical + swap or whatever) the kernel randomly kills processes to make
room. So a disappearing postmaster is not necessarily a sign of a fault
on PostgreSQL's part. I'm not sure how to configure the kernel in this
area, I just recall the discussion on the kernel mailing list about
whether the init process would be allowed to be randomly killed as well.
(I kid you not.)
