运行命令时docker-compose找不到要注入到Postgresql的文件

我正在尝试将.backup文件还原到Postgresql数据库。为此，我使用docker-compose文件启动postgres docker容器：

docker-compose.yml

   postgresql:
     image: postgres
     restart: always
     ports:
       - "5432:5432"
     environment:
       - POSTGRES_USER:postgres
     # - PGDATA:/var/lib/postgresql/data/pgdata/
     volumes:
       - ${PWD}/project/data/MX/bkup/data:/var/lib/postgresql
     command: 
       - pg_restore -U postgres -d postgres /var/lib/postgresql/ph.backup

当我使用以下命令运行docker-compose文件时：

docker-compose up postgresql

我收到错误：

   postgresql:
     image: postgres
     restart: always
     ports:
       - "5432:5432"
     environment:
       - POSTGRES_USER:postgres
     # - PGDATA:/var/lib/postgresql/data/pgdata/
     volumes:
       - ${PWD}/project/data/MX/bkup/data:/var/lib/postgresql
     command: 
       - pg_restore -U postgres -d postgres /var/lib/postgresql/ph.backup

即使文件在卷中，也会发生这种情况

(virtual) med@nid:~/projects/project/pkg$ docker-compose up postgresql
