[nagios btcpayserver-02] User name was not found - postgres
after anarcat's work on btcpayserver, nagios has been complaining that btcpayserver-02 doesn't have a postgres user. i checked, and it sure doesn't; because postgres is running in docker now.
the obvious solution is to remove the nagios postgres check, though that might have unintended consequences like removing additional checks that we do want to keep around. so it might be better to just mark this check as acknowledged and let it sit as-is.
