你是否多次尝试，并在同一位置遇到相同的错误？

好问题，@pfaffman。

同样的错误，但崩溃的位置不同。

ActiveRecord::StatementInvalid: PG::ConnectionBad: PQconsumeInput() 服务器意外关闭了连接
	这可能意味着服务器在处理请求之前或处理过程中异常终止。
: SELECT  "user_uploads".* FROM "user_uploads" WHERE "user_uploads"."user_id" = 1221 AND "user_uploads"."upload_id" = 28216 LIMIT 1

你是如何安装 Discourse 的？

5

这本身并非崩溃：

PostgreSQL 数据库消失这种情况我们通常不会遇到。

您是如何安装的？您的设置有什么不同或自定义的地方？

非常标准的 云安装。
以下是 discourse-doctor 的输出。
