我正在尝试在带有 odoo 的 docker 容器中使用 shell，但我遇到了一些问题。
我通过 docker-compose 设置本地环境，更准确地说，我在一个网络中运行 odoo 和 PostgreSQL，但是当我想为 odoo shell 指定 db 时，它不起作用。
这是我的 docker-compose.yaml：
version: '3'
services:
db:
image: postgres:10
ports:
- '5432:5432'
environment:
- POSTGRES_USER=odoo
- POSTGRES_PASSWORD=odoo
- POSTGRES_DB=postgres
volumes:
- odoo-db-data:/var/lib/postgresql/data
odoo:
depends_on:
- db
build: .
ports:
- '8069:8069'
- '8071:8071'
- '4444:4444'
volumes:
- odoo-web-data:/var/lib/odoo
- ./local_addons/:/mnt/extra-addons/
- ./odoo.conf:/etc/odoo/odoo.conf
stdin_open: true
tty: true
volumes:
odoo-web-data:
odoo-db-data:
和 Dockerfile（这很简单）：
FROM odoo:13
USER root
RUN pip3 install remote-pdb pdbpp dateutils xlrd
USER odoo
odoo 实例本身工作得很好，因此 odoo 必须能够连接到数据库。但是当我尝试像这样执行shell时：
docker exec -it odoo_odoo_1 bash -c "odoo shell -d postgres"
我有这个例外（为了便于阅读，跟踪未满）：

psycopg2.OperationalError: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
我没有明确指定 postgres 主机和端口（这是我的 odoo.conf）：
[options]
addons_path = /mnt/extra-addons
data_dir = /var/lib/odoo
debug_mode = True
; db_host = db
; db_port = 5432
; db_user = odoo
; db_password = odoo
; db_name = postgres
你有什么想法为什么我无法连接到数据库？
