I am trying to install postgresql via a playbook and want to make sure the service 
is not running prior installation on the target (rhel7/8 & debian10) machines.

However my task below

      - name: stop postgresql.service from systemd if running
        service:
          name: postgresql.service
          state: stopped
          # enabled: false
        become: yes

is failing ('Could not find the requested service postgresql.service: host')

so, I guess I have to build something that directs the target to ignore that 
and continues with the playbook. I just can't see anything

You can check the status of the postgresql service as follows:

   - service_facts:

   - debug:
       msg: "{{ ansible_facts.services.postgresql | default({ 'state' : 'absent'}) 
}}"

TASK [service_facts] 
***************************************************************************************************************************************
ok: [papas]

TASK [debug] 
***********************************************************************************************************************************************
ok: [papas] => {
      "msg": {
          "name": "postgresql",
          "source": "sysv",
          "state": "running"
      }
}

are those arguments to the the "service" module? how exaclty would I weave 
those into my task? I tried

   - name: stop postgresql.service from systemd if running
     service:
       name: postgresql
         service_facts:
         debug:
           msg: "{{ ansible_facts.services.postgresql | default({ 'state' : 
'absent'}) }}"
       state: stopped
       # enabled: false
     become: yes

but that did not work

No, use my tasks verbatim.
