Well, your log doesn't show any evidence to support the claim that
Postgres wasn't running.  We see some child processes having minor trouble
while exiting, and one that failed while trying to start up; the latter
being strong evidence that the postmaster was still working at least.

So in short, you haven't given us a complete description of what happened.
What led you to decide you needed to restart Postgres?
