PostgreSQL 10 到 PostgreSQL 13 的更新失败

[CamilleRoux]

我注意到需要先停止数据容器：

如果您使用的是我们 discourse_docker 仓库中提供的示例所构建的专用数据容器，请务必以安全、干净的方式关闭 PostgreSQL。

如今，我们有后台作业在运行跨越数分钟的查询，因此关闭 Web 容器将有助于安全地关闭数据容器。

./launcher stop web_only
./launcher stop data
./launcher rebuild data
./launcher rebuild data
./launcher rebuild web_only

这是我停止两个容器后运行 tail -f shared/data/log/var-log/postgres/current 得到的输出：

这很可能就是问题的根源，我该如何修复？
