我正在使用Heroku文档中的要求进行备份。
pg_dump -Fc --no-acl --no-owner --no-privileges -h [HOST] -U [DB_USER] [DB_NAME] > backup.dump
当我像这样恢复时（文件的大小约为100MB）：
heroku pg:backups --app [APP_NAME] restore 'https://[DUMP_URL]' [HEROKU_DATABASE_URL]
上传进度停止在19.4MB并记录状态后，收到错误消息：
$ heroku pg:backups --app [APP_NAME] info r081

我首先想到的可能是由于包含BLOBS的表文件。但我似乎无法理解为什么它应该是一个问题。最大的文件是4MB。 日志还说明100MB中只有19.4已经导入。
