Heroku DB部署

Question

我正在尝试第一次Heroku部署，遇到了麻烦

heroku pg:backups:restore "https://s3.us-east-2.amazonaws.com/myusername/POSTGRESQL.dump" 
                          DATABASE_URL --app MyAppName

我收到错误

 !    An error occurred and the backup did not finish.
 !
 !    pg_restore: [archiver] did not find magic string in file header
 !    pg_restore finished with errors
 !    waiting for download to complete

有时错误是：

我已经从各种浏览器中确认该网址可供公众使用，并且可以下载该文件。我按照Windows的建议在URL周围使用双引号，这是我做错了什么？

Answer 1

我面临同样的问题。结果是我的转储文件有问题。我没有正确压缩它。

--format=c选择 custom 作为格式输出（与 相同-Fc）。它默认压缩文件，但这还不够，所以我也使用了--compress标志。

这个标志告诉压缩的级别；它从 0（较轻）到 9（较重）。

我用了 9，以防万一，我的命令最终就是这样

pg_dump --format=c --compress=9 --no-acl --no-owner -h THE_HOST -U YOUR_USER THE_DATABASE > YOUR_FILE.dump

它奏效了。

Answer 2

最后我不知道如何导入到 Heroku，因为他们宣传可以在https://devcenter.heroku.com/articles/heroku-postgres-import-export#import上完成

因此，我使用了 DBeaver 等数据库连接客户端，将数据库转储转换为 SQL 脚本，并手动运行该脚本来导入数据。
