我正在使用官方的Postgres泊坞窗图片，并且我已经添加了一个shell脚本，该脚本应该在启动服务器之前加载备份（请按照＆＃39;如何扩展此图像＆＃39; 39;在this page上
我的加载备份脚本如下：
gosu postgres pg_ctl start -w -D /var/lib/postgresql/data
gosu postgres psql -d postgres -f /dump/dump.sql
gosu postgres pg_ctl stop -w -D /var/lib/postgresql/data
然后Postgres图像自动调用postgres以启动服务器实时。
从我的日志中我知道psql和postgres命令都运行良好，但当我进入psql（docker exec -it CONTAINER_ID psql -U postgres），我\c进入正确的数据库并\dt列出关系，什么都没有！
为什么会发生这种情况？
我确实收到了以下错误（由docker logs CONTAINER_ID | grep "^[A-Z]*:\s"找到），但我不知道该怎么做。某些功能或扩展是否存在无关紧要？在这种情况下，我没有使用它们：

为什么在执行加载脚本之前不尝试安装此扩展？这样的事情：
<强> Dockerfile
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get install -y postgresql-plpython3-9.4
加载脚本
gosu postgres pg_ctl start -w -D /var/lib/postgresql/data
gosu postgres psql -d postgres -c "create language 'plpythonu3';"
gosu postgres psql -d postgres -f /dump/dump.sql
gosu postgres pg_ctl stop -w -D /var/lib/postgresql/data
