尝试为postgres设置wal-e。
遵循各种教程，我最终要做一个干净的9.6 postgres安装的第一次备份。
遵循一些教程，最后阅读初始wal-e backup-push，如下所示：
sudo -u postgres -i
envdir /etc/wal-e.d/env wal-e backup-push /var/lib/postgresql/9.6/main
我希望命令能够快速终止，因为它是一个空的数据库。
然而它似乎无限期地等待。显示waiting for required WAL segments to be archived

说实话，我有点超出我的深度。 Afaik，上面应该做一个初始备份，但不要等待显然不断更新的WAL文件。 （我在我的postgres配置中有archive_mode=on并设置archive_command = 'envdir /etc/wal-e.d/env wal-e wal-push %p'哪个应该进行增量推送。再次afaik。）。
如何完成此初始备份命令？
