Answer 1

您可以导出本地数据库的副本并将其导入 Heroku，而不是这样做。

对于从本地数据库导出，

pg_dump <DATABASE_NAME> > <FILENAME>.sql 

这将要求您输入数据库密码。但在 Windows 中，这会询问用户密码，因为默认用户名是系统用户名。为此，您必须指定您的用户名

pg_dump -U <USER_NAME> <DATABASE_NAME> > <FILENAME>.sql 

对于您的情况，命令将如下所示：

pg_dump -U postgres gce > gce.sql 

本地数据库导出后，可以直接上传到heruko。

heroku pg:psql --app <APP_NAME> < gce.sql
