This message indicates that the backend got a SIGTERM signal from
someplace. If the postmaster got a SIGINT signal it would turn around
and SIGTERM all the backends, but there's no other mechanism in Postgres
that would cause this to happen.

Is the postmaster still alive after the backends shut down, or does it
quit too? What shows up in the postmaster's stderr log? (If you're
sending stderr to /dev/null, now is a good time to stop doing so.)
