Ugh. There's not a lot we can do about the kernel deciding to kill us.

Perhaps you should talk to the kernel developers about why they can't
find more graceful ways of dealing with out-of-memory situations :-(
I am not sure exactly what Linux considers an out-of-memory situation.
If it's dependent on available swap space, then configuring more swap
would probably prevent this scenario. If only physical RAM counts,
you might need to buy more RAM, or configure Postgres with a smaller
shared_buffers value.
