Question

好的，问题出在这里：我想上传一个我在本地使用的数据库，我在localhost中使用，但是，当我使用时：

PGPASSWORD=mypassword pg_dump -Fc --no-acl --no-owner -h localhost -U root app_db > app_db.dump

我总是得到：

pg_dump: [archiver (db)] connection to database "app_db" failed: could not connect to server: Connection refused
 Is the server running on host "localhost" and accepting
 TCP/IP connections on port 5432?
could not connect to server: Connection refused
 Is the server running on host "localhost" and accepting
 TCP/IP connections on port 5432?
could not connect to server: Connection refused
 Is the server running on host "localhost" and accepting
 TCP/IP connections on port 5432?

我认为问题在于我正在编写localhost而不是我的heroku应用程序地址，有人能告诉我如何才能获得正确的地址？
