我正在尝试使用Heroku上的其他人开发的网络应用。拉动源代码后，我在我的计算机上安装了PostgreSQL 9.3。
尝试在Heroku上导入现有数据库，但它似乎不起作用：
$ export HEROKU_POSTGRES_IVORY_URL=postgres:///$(user)
尝试使用我的database.yml文件中的以下设置：
development:
adapter: postgresql
database: app-dev
host: localhost
username: user
password: (password created when installing PostgreSQL)
但是当我尝试在本地运行应用程序时，这会产生以下错误：

我一遍又一遍地看过Heroku的指示，似乎无法找到解决方案。我对此比较陌生，所以一些指针会非常感激！
我正在使用Ruby on Rails开发一个应用程序，我正在使用Windows。
答案 0 :(得分：0)
我建议首先检查pg_hba.conf文件，对于windows应该位于：
C:\Program Files\PostgreSQL\9.3\data\pg_hba.conf
在文件的底部，您应该看到以下内容：
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
你的conf文件与上面的内容有很大不同吗？
