Question

在尝试将我的数据库从我的development.sqlite3文件推送到我的Heroku应用程序时，我遇到以下错误消息：

pg_dump: [archiver (db)] connection to database "development" failed: could not connect to server: Connection refused
    Is the server running on host "localhost" (::1) and accepting
    TCP/IP connections on port 5432?
could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting
    TCP/IP connections on port 5432?
pg_restore: [archiver] input file is too short (read 0, expected 5)
psql: could not connect to server: Connection refused
    Is the server running on host "localhost" (::1) and accepting
    TCP/IP connections on port 5432?
could not connect to server: Connection refused
    Is the server running on host "localhost" (127.0.0.1) and accepting

 !    Heroku client internal error.

我是Heroku的新手，无法想出这个。希望它是简单的我忽略的。

首先，sqlite并不打算用于生产。事实上，Heroku不支持使用sqlite，因此如果你想将你的应用程序与Heroku一起使用，你需要切换到Postgres：https://devcenter.heroku.com/articles/getting-started-with-rails4#write-your-app。

您获得的具体错误是因为您的heroku应用程序要连接到端口5432，默认情况下由Postgres使用，而sqlite不使用。但是，由于您没有要在localhost上连接的PG服务器，因此您的应用程序失败并显示该错误。

pg_dump：[archiver（db）]与数据库“development”的连接失败：无法连接到服务器：Connection拒绝
