恢复问题：关系 "theme_fields" 不存在

adrelanos · 2020 年5 月 25 日 13:43

感谢您的帮助！

我已从仍完全正常运行的旧生产服务器创建了新备份。

已在新阶段服务器上清除了 Docker 和 Discourse。按照官方说明重新安装了 Docker 和 Discourse。随后执行了命令行恢复说明。

该备份是使用 docker-engine 17.05.0~ce-0~debian-stretch 创建的，而恢复环境使用的是 docker-ce-cli 5:19.03.9~3-0~debian-buster。这也导致了 PostgreSQL 版本的更新（旧版本：10；新版本：12）。

备份过时的 Docker/PostgreSQL 版本，然后尝试在最新版本的 Docker/Discourse 安装上进行恢复，这种做法是否合理？

这次遇到了不同的错误。

我想知道这怎么可能，因为我的旧生产 Discourse 服务器仍然完全正常运行。而且这是我尝试的第二个备份。

是 PostgreSQL 10 还是 PostgreSQL 12？
