我们建议您测试该流程，因为这并非我们支持的功能，但很可能您只需执行升级操作即可顺利解决。

我刚刚完成了 PostgreSQL 18 的标准安装以及 双容器 配置，整个过程非常顺利，没有任何问题。再次感谢 @chrisr 和团队提供的简易指南。

对于配置在 Cloudflare CDN 后面并使用 R2 进行上传/备份的双容器环境，我使用的步骤如下：

第一步：磁盘清理

# 清除所有未使用的 Docker 数据
docker system prune -a -f

# 清除旧日志和 apt 缓存
journalctl --vacuum-time=2d
apt-get clean
apt-get autoremove -y

# 检查数据库大小
du -sh /var/discourse/shared/data/postgres_data

# 检查新的可用空闲空间
df -h -x tmpfs -x devtmpfs

第二步：维护与备份

  1. 编辑 Cloudflare 维护页面，显示“15-20 分钟系统维护更新”，并设置自动刷新计时器（可能不会花这么长时间，但以防万一！）。开启一个 Cloudflare Worker 路由以显示维护页面。

  1. 通过命令行触发备份：
cd /var/discourse
./launcher enter web_only
discourse backup
exit
  1. 登录 Cloudflare R2 控制台并检查备份文件夹，确认备份文件已成功上传。

第三步：安全关机

  1. 首先停止 Web 容器以断开所有活动连接，然后停止数据库容器：
cd /var/discourse
./launcher stop web_only
./launcher stop data
  1. 验证 PostgreSQL 是否正常关闭：
tail -n 20 shared/data/log/var-log/postgres/current

第四步：升级重建

按以下顺序运行命令：

./launcher rebuild data # 导出、迁移并恢复 PostgreSQL 18
./launcher rebuild data # 重建数据库容器
./launcher rebuild web_only # 重建 Web 应用

第五步：优化与清理

  1. 生成缺失的 pg18 表统计信息，否则论坛速度会比平时慢：
docker exec -u postgres data /usr/lib/postgresql/18/bin/vacuumdb -d discourse --analyze-in-stages
  1. 测试论坛以确保一切正常运行——如果你设置了自动刷新计时器，此时维护页面应该不再显示。
  2. 删除指向维护页面的 Cloudflare Worker 路由（我们不想触及每日 100,000 次的限制！）
  3. 删除旧的 pg18 数据以释放磁盘空间：
rm -fr /var/discourse/shared/data/postgres_data_old/

完成！ :partying_face: :clinking_beer_mugs:

对于第 1 点，你需要在容器内挂载额外的空间供升级过程使用，但我认为你仍然需要绕过空间检查？

我觉得这可能是一个“先有鸡还是先有蛋”的问题。

如果你的暂存站点使用的是不同的数据库，那么它并没有真正检查所有内容？如果你坚持这样做，请备份数据，删除 postgres_data，然后使用空数据库重建容器，再恢复备份。

但你真正应该做的是创建新的 pg18 服务器，将暂存站点指向该服务器以验证其正常工作，然后将生产站点迁移到该服务器。

我在更新时收到了以下错误信息：

Stopping PostgreSQL 15 database server:
main.Stopping PostgreSQL 18 database server:
mainError: The cluster is owned by group id 993 which does not exist ... failed!
failed!

解决此问题的窍门是删除旧的升级残留文件，并修正权限：

rm -rf /var/discourse/shared/standalone/postgres_data_new
chown -R 999:999 /var/discourse/shared/standalone/postgres_data

… 然后运行两次 ./launcher rebuild app，如果迁移成功且一切正常，可以可选地运行 ./launcher cleanup。

希望这能帮到你。:slight_smile:

我在 Windows 上使用 DevContainers 运行开发环境，有什么办法可以修复这个错误吗？
