RHEL 7 (systemd) reboot

I am running three instances (under different users) on a RHEL 7 server to support a vendor product.

In the defined services, the start & stop scripts work fine when invoked with systemctl {start|stop} whatever.service but we have automated monthly patching which does a reboot.

Looking in /var/log/messages and the stop scripts do not get invoked on reboot, therefore I created a new shutdown service as described here<https://unix.stackexchange.com/questions/211924/effect-of-reboot-signal-on-systemd-service-state>.

It appears that PostGreSQL is receiving a signal from somewhere prior to my script running...

The database must be available for the product to shut down in a consistent state.

I am open to suggestions.

Thanks,
