The error message This example is done using WSL 2 with a Linux-based application.
The below error message is displayed:
System has not been booted with systemd as init system (PID 1). Can't operate.

How to fix it
To fix, operate the service using /etc/init.d/ instead:
sudo /etc/init.d/<service> <operation>
Where the operation is start, status, stop, restart, etc and service is the service you need to operate.

sudo /etc/init.d/postgresql start
