Ansible-role-postgresql: postgres غير قادر على تسجيل الدخول للتحقق من وجود قاعدة البيانات

لست متأكدًا من أنني أفهم كيف أو لماذا لا يتمكن المستخدم postgres من تسجيل الدخول للتحقق من وجود قاعدة البيانات أم لا ، ولكن دليل التشغيل التالي ...

---
- hosts: concourse_db
  roles:
    - role: geerlingguy.postgresql
      tags:
        - concourse_db
      vars:
        postgresql_restarted_state: "restarted"
        postgresql_service_state: started
        postgresql_service_enabled: true
        postgresql_hba_entries:
          - { type: local, database: all, user: postgres, auth_method: peer }
          - { type: local, database: all, user: all, auth_method: peer }
          - { type: host, database: all, user: all, address: '127.0.0.1/32', auth_method: md5 }
          - { type: host, database: all, user: all, address: '::1/128', auth_method: md5 }
        postgresql_locales:
          - 'en_US.UTF-8'
        postgresql_databases:
          - name: concourse
            owner: concourse
            login_user: postgres
            state: present
        postgresql_users:
          - name: concourse
            password: concoursepassword
            encrypted: true
            db: concourse
            login_user: postgres
            state: present
...

اكتب الأخطاء التالية:

TASK [geerlingguy.postgresql : Ensure PostgreSQL is started and enabled on boot.] ***************************************************************************************************
ok: [10.144.0.137]

TASK [geerlingguy.postgresql : Ensure PostgreSQL databases are present.] ************************************************************************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ProgrammingError: role "concourse" does not exist
failed: [10.144.0.137] (item={'name': 'concourse', 'owner': 'concourse', 'login_user': 'postgres', 'state': 'present'}) => {"changed": false, "item": {"login_user": "postgres", "name": "concourse", "owner": "concourse", "state": "present"}, "msg": "Database query failed: role \"concourse\" does not exist\n"}
    to retry, use: --limit @/Users/pd028300/Documents/development/Ansible/concourse_ci_playbook/playbook_2.retry

لست متأكدًا مما إذا كان من المفترض أن يستخدم المستخدم postgres أو المستخدم الذي أنشأته ، concourse في هذه الحالة.
