我正试图从Windows中将我的postgres数据库拉入Heroku。我跑
$app_folder> heroku db:push postgres://postgres:password@localhost/db_name
它正确地将模式和一些数据发送到表，但后来我收到了以下错误。
19 tables, 1,835 records
Saving session to push_201110201435.dat..

我在Github上找到了这个帖子，但它没有解决我的问题：https://github.com/ricardochimal/taps/issues/86
有人可以帮忙吗？

在搜索和尝试一些事情后很多时候我注意到我没有添加数据库插件。 （Heroku说每个应用程序都带有数据库，所以我没想到我必须激活插件）
简单：
heroku addons:add shared-database
解决了一切。
希望它可以帮助任何人

假设您已经添加了一个数据库并且仍然遇到此问题，请确保您至少运行了1个Dyno，并且您已经升级了数据库。
要宣传数据库，请先运行以下命令获取其名称：
heroku pg
它会被称为HEROKU_POSTGRESQL_COLOR_URL，然后只是宣传它：
heroku pg:promote HEROKU_POSTGRESQL_COLOR_URL
这将允许您通过DATABASE_URL环境变量访问该数据库，这是db：push命令用来推送到的。
