You don't need a temp table for that. You can create the array directly from the new and old records:

    v_message := array[concat_ws(',', 'empName', old.empname, new.empname), concat_ws(',', 'location', old.location, new.location)];

Although nowadays I would probably pass such an "structure" as JSON though, not as a comma separated list.
