嘗試將Heroku數據庫下載到本地：連接數據庫失敗

Question

我正在按照本文檔嘗試將Heroku數據庫拉到本地主機。 我已經成功運行了heroku pg:backups:capture和heroku pg:backups:download並在我的文件結構中看到了latest.dump文件。

但是，當我嘗試運行pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myuser -d mydb latest.dump ，出現以下錯誤：

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?

誰能幫我找出解決方法？

要在還原期間創建mydb數據庫，您需要--create選項。 否則，該命令將根據錯誤消息查找名為mydb的現有數據庫，該數據庫似乎不存在。
