I don't think it'd be good to switch to postgres daemonizing itself. If
we were starting fresh, maybe, but there's plenty people invoking
postgres from scripts etc. And tools like systemd don't actually want
daemons to fork away, so there's no clear need from that side either.

Yes, the OOM issues are still relevant.
