Question

After establishing a database using heroku addons:create heroku-postgresql:hobby-dev, I tried to migrate my local database to heroku database. So I first ran

heroku python manage.py migrate. After that I created a dump file of my local database using pg_dump -Fc --no-acl --no-owner -h localhost -U myuser mydb > mydb.dump. I uploaded my mydb.dump file to dropbox and then used the following command to load the dump to my heroku database

 heroku pg:backups restore'https://www.dropbox.com/s/xkc8jhav70hgqfd/mydb.dump?' HEROKU_POSTGRESQL_COLOR_URL

But, that throws the following error -

 r004 ---restore---> HEROKU_POSTGRESQL_PURPLE
 [0KRunning... 0.00B..
 [0KAn error occurred and your backup did not finish.
 Please run `heroku pg:backups info r004` for details.

And on running heroku pg:backups info r004 I get -

Database:    BACKUP

Finished:    2015-06-25 18:19:38 +0000

2015-06-25 18:19:38 +0000: waiting for download to complete
2015-06-25 18:19:38 +0000: download done

There is not much information on this error online and I can't figure out what the problem is.

Answer 1

如果数据库很小并且你觉得这很幸运，那么

pg_dump --no-acl --no-owner -h localhost -U myuser myd | heroku pg:psql

Answer 2

我也有这个错误，我的解决方案有点不同。问题与使用的格式有关。转储数据库时我需要使用--format = c。

为了解决这个问题，我使用--format = c

再次转储数据库

pg_dump --no-acl --no-owner --format=c database_name > db.dump

然后将其导入我的heroku应用

heroku pg:backups restore 'url_for_db.dump' DATABASE_URL

希望这可以帮助将来的某个人！
