You can use this to provide us some extra information about the size of your db when asking for help that may be related to db size.

how can we know (whole) database size?
While all db tables are there, whole DB size hasn’t been shown/told in this anywhere.

这并非 Discourse 特有，你可以运行以下命令来查看整个数据库的大小：

./launcher enter app
rails db
SELECT pg_size_pretty(pg_database_size(current_database()));

谢谢。
我通过该命令成功查看了数据库大小。

但之后，为了体面地退出 Rails 控制台，我按了 Ctrl+Z。
结果它却弹出了这条消息让我有些惊讶：

discourse-> 
^Z[1]+  Stopped                 rails db

然后，当我按 exit 退出时，它提示“存在已停止的作业”，随后返回到正常的白色提示符，于是我关闭了窗口。

我对这两条消息感到有些担心。我该怎么办？
