试图将Heroku数据库下载到本地：连接到数据库失败

Question

我正在关注this文档，试图将我的Heroku数据库拉到我的本地主机。我已成功运行heroku pg:backups:capture和heroku pg:backups:download，并在我的文件结构中看到latest.dump文件。

然而，当我尝试运行pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myuser -d mydb latest.dump我得到以下错误：

pg_restore: connecting to database for restore 
pg_restore: [archiver (db)] connection to database "mydb" 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? 

谁能帮助我弄清楚如何解决这一问题？

要在恢复期间创建mydb数据库，您需要--create选项。否则，根据错误消息，该命令会查找名为mydb的现有数据库，该数据库似乎并不存在。
