polardb-pg容器连接数据库错误

name: polardb

services:
  polardb_pg:
    restart: always
    image: polardb/polardb_pg_local_instance:15
    container_name: polardb-pg
    environment:
      POLARDB_USER: polar
      POLARDB_PASSWORD: '!XXXXXX'
      TZ: Asia/Shanghai
    volumes:
      -  ./polardb-pg/:/var/polardb
    ports:
      - 54320-54322:5432-5434

这是我的compose.yaml(用户名和密码不是真实的)，执行

docker compose up -d

创建了polardb-pg容器,并且存活着，但是psql无法连接

docker exec -it polardb-pg psql

出现报错:

psql: error: connection to server at "127.0.0.1", port 33081 failed: Connection refused
        Is the server running on that host and accepting TCP/IP connections?

这个33081到底是什么情况...
具体情况如下：
