Question

我正在尝试将我的postgres数据库从九倍迁移到heroku。

我用来导出的命令是：

PGPASSWORD=password pg_dump -h ipaddress -p port -U user -d database -Fc --no-acl --no-owner -x -O -N postgis > ninefold-backup.dump

然后上传到S3，然后运行此命令：

heroku pg:backups restore 'https://s3-us-west-2.amazonaws.com/bucket/ninefold-backup.dump' DATABASE_URL -a app --confirm app

然后heroku报道：

An error occurred and your backup did not finish.

Please run `heroku pg:backups info r003` for details.

在日志中显示如下错误：

我错过了什么？

找到了办法。 Ninefold使用的扩展似乎存在一些问题，因此通过添加-n public选项，它将仅创建备份公共模式。

PGPASSWORD=password pg_dump -h ipaddress -p port -U user -d database -Fc --no-acl --no-owner -x -O -N postgis -n public > ninefold-backup.dump

如何从Ninefold导出Heroku友好的Postgres转储？
