Yeah, there's some danger in kill -9 to the postgres processes, but
I've had to killall -9 -f postgres once or twice in the distant past.
The -m immediate is the signal just this side of kill -9, forget the
name. You should be ok.
Definitely look into what's causing the oom killer to come out and

turn it off)
