How are you getting it started after the reboot? If you're not using systemd facilities (eg. if you're calling pg_ctl on your own script), systemd may be getting confused about what's the status of the service and stopping it on its own.
systemctl start postgresql-11
Plus I've run systemctl enable postgresql-11
Also, what are the timestamp differences between the final "redirecting log output" line and the "Failed to start" lines?
0 second difference.
Not sure what's happend. Re-installed a second time. Now it has survived pass three reboots and seems happy. Was just odd that there wasn't any error message as to why it failed.
As an aside to the person asking about changing back the hostname.
I re-installed using the new hostname and it still failed once.
