Currently to wait for a process to be up you can write while loop:

while `ps aux | grep [p]ostgres`; do sleep 1s; done #syntax i should always google

But it would be nifty to do it like:

wait-on process:postgres for ps | grep alike and wait-on systemd:postges for systemctl status postgres.service | grep running
