Postgresql 在docker下添加psql时出现清单未知错误

我在docker php/postgres/phppgadmin中创建了一个脚本，我需要将psql添加到我的项目中以上载我的sql转储。 我找到了它并将其添加到我的项目中，但运行build命令时出现错误：

docker-compose up -d --build
... 
Sccessfully built 3b0700d7bed8
Successfully tagged lprodsdocker_web:latest
Pulling psql (softwareplant/psql:latest)...

My docker-compose.yml：

version: '3'

services:

    web:
        build:
            context: ./web           # directory of web/Dockerfile.yml

        command: composer install  --ignore-platform-reqs

哪条路正确？就有这样的形象。。。 无效吗？你能给我一些其他的建议吗

已修改： 下一步我试试

https://hub.docker.com/r/governmentpaas/psql
Provides psql Postgres client. 

description seems like what I need : to upload dump into postgres db
In docker-compose.yml I added item :

    psql:
        image: governmentpaas/psql
        environment:
            - PHP_PG_ADMIN_SERVER_HOST=db
            - PHP_PG_ADMIN_SERVER_PORT=5432
            - PHP_PG_ADMIN_SERVER_DEFAULT_DB=postgres
        container_name: lprods_psql

        restart: always
        ports:
            - "8088:80"
            - "444:444"
        links:
            - db

它已经安装好了，我在托管操作系统中看到了这个容器：

lprods_docker$ docker ps
CONTAINER ID        IMAGE                       COMMAND                  CREATED             STATUS                          PORTS                                        NAMES

但在输入bash容器时未找到psql命令：

# uname -a
Linux 7071eaf067d6 4.15.0-66-generic #75-Ubuntu SMP Tue Oct 1 05:24:09 UTC 2019 x86_64 GNU/Linux
root@7071eaf067d6:/var/www/lprods_docker_root# whereis psql

# psql -v
bash: psql: command not found

这是我需要的图像吗？如果是，如何使用？

您必须指定图像的标签，例如：

version: '3'

services:

[...]

    psql:
        image: softwareplant/psql:dev-jira7

[...]

softwareplant/psql似乎是postgresql server，为什么需要2个数据库？看起来这是一个无效的包。当我需要将sql转储上传到dbname数据库中时，使用posgtres命令，比如psql-h localhost-d dbname-U postgres-W。但是在我的web容器中，我没有psql命令。如何安装？请看修改块
