您好 Discourse 社区，
我在执行后台作业时遇到了 Discourse 设置问题，具体来说是执行后台作业时。此错误不会影响论坛的前端，前端运行正常。
/admin/logs 中的错误消息如下：
Message
Job exception: We could not find your database: community. Which can be found in the database configuration file located at config/database.yml.
To resolve this issue:
- Did you create the database for this app, or delete it? You may need to create your database.
- Has the database name changed? Check your database.yml config has the correct database name.
To create your database, run:
bin/rails db:create

前端数据库运行良好：
社区使用单独的 PostgreSQL 服务器。
如何解决此问题？谢谢。
