面向自托管用户的 PostgreSQL 18 更新

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。

[Lilly (Lillian)]

我刚刚完成了 PostgreSQL 18 的升级，无论是标准安装还是 双容器配置，整个过程都非常顺利，没有任何问题。再次感谢 @chrisr 和团队提供的简便教程。

对于位于 Cloudflare CDN 之后、并使用 R2 上传/备份存储桶的双容器配置，我使用的步骤如下：

步骤 1：磁盘清理

# 删除所有未使用的 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

步骤 2：维护与备份

1. 编辑 Cloudflare 维护页面，显示“系统维护更新，预计需要 15-20 分钟”（实际可能不需要这么久，但为了安全起见最好预留时间），并设置约 30 秒的重新加载计时器。开启 Cloudflare Worker 路由以显示维护页面。

2. 通过命令行触发备份：

cd /var/discourse
./launcher enter web_only
discourse backup
exit

3. 登录 Cloudflare R2 控制台，检查备份文件夹以确认备份文件已成功上传

步骤 3：安全关闭

1. 首先停止 Web 容器以终止所有活动连接，然后停止数据库容器：

cd /var/discourse
./launcher stop web_only
./launcher stop data

3. 验证 PostgreSQL 是否正常关闭：

tail -n 20 shared/data/log/var-log/postgres/current

步骤 4：升级重建

按以下顺序执行命令：

./launcher rebuild data # 转储、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

步骤 5：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

2. 测试论坛以确保一切正常运行 - 如果你设置了重新加载计时器，此时维护页面应该不再加载了。
3. 移除指向维护页面的 Cloudflare Worker 路由（我们不想触及每日 100,000 次的限制！）
4. 删除旧的 pg18 数据以回收磁盘空间：

rm -fr /var/discourse/shared/data/postgres_data_old/

完成！

[pfaffman (Jay Pfaffman)]

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。

[Tobias_1 (Tobias)]

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。

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？

也许是猜测，但 Discourse 是否将它们混淆了？

编辑：在 ChatGPT 的帮助下已修复。我不是 Linux/Postgres 专家。

[kcahtoor]

我遇到了一个问题，PostgreSQL 18 缺失或者没有迁移我的 secondsite 数据库。如有任何帮助，将不胜感激。

[chrisr (Chris Rendle-Short)]

我有一个针对损坏的多站点升级的修复方案正在等待中，准备好后我会通知你。

[chrisr (Chris Rendle-Short)]

我刚刚合并了一个针对多站点的修复，所有数据库现在应该都能正常升级。您可以按照以下步骤将数据库恢复到升级前的状态，然后重试：

1. 确认旧数据仍存在于 /shared/postgres_data_old。
2. 删除 /shared/postgres_data 中升级失败的数据（如果磁盘空间充足，建议先重命名而不是直接删除）。
3. 将 /shared/postgres_data_old 重命名回 /shared/postgres_data。您还需要确保目录权限为 0700，否则 Postgres 将拒绝使用它。
4. 运行 ./launcher rebuild app 重新启动升级。

[Moin]

我认为他们几个小时前已经解决了这个问题

升级到最新版后，所有数据都丢失了

所以我检查了 PostgreSQL 模板文件。它只针对一个数据库。这太荒谬了。它本应该遍历现有的数据库并对其进行更改。我把这个留在这里，供任何在此场景下寻找解决方案的人参考 DB_LIST=$(su postgres -c "/usr/lib/postgresql/${PG_MAJOR_OLD}/bin/psql -p 5432 -tAc \"select datname from pg_database where not datistemplate and datname != 'postgres'\"") for DB in $DB_LIST; do su postgres -c "/usr/lib/postgresql/${PG_MAJOR_OLD}/bin/pg_dump -Fd -j$(nproc --ignore=1) \"$DB\" -f /shared/postgres_dump/\"$DB\"" done

[kcahtoor]

非常感谢。

[peternlewis]

我在重建日志中注意到了这一点：

116:C 11 Aug 2026 06:43:27.336 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see vm.max_map_count growing steadily when vm.overcommit_memory is 2 · Issue #1328 · jemalloc/jemalloc · GitHub. To fix this issue add ‘vm.overcommit_memory = 1’ to /etc/sysctl.conf and then reboot or run the command ‘sysctl vm.overcommit_memory=1’ for this to take effect.

这是否需要担心？

[peternlewis]

我还注意到，我的新数据库大小明显小于旧数据库：

root@Forum:/var/discourse/shared/standalone# du -sh postgres_data postures_data_old
6.8G  postgres_data
10G   postgres_data_old
17G	total

这是否令人担忧？

[merefield (Robert)]

@peternlewis

postures_data_old

这目录名有点奇怪？

作为对比，我的结果如下：

:/var/discourse/shared/data# du -sh postgres_data postgres_data_old
4.1G    postgres_data
3.4G    postgres_data_old

[peternlewis]

@merefield

这目录名有点奇怪？

嗯，我想是类型修正把这个名字弄乱了。应该是 postgres_data。

所以你的新数据变大了。这有点令人担心。

[Andrew_Rowe]

按照说明运行了更新，一切都非常顺利。第一次重建后，控制台显示来自 15 的更新成功，并显示了旧数据库的位置以及再次运行重建的说明。

感谢 Lilly 的提示

@Lilly

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

得以确认磁盘空间充足

编辑：补充

感谢所有为此出色工作付出努力的人

[Ed_S]

@Lilly

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

我可能会加上通配符，以防升级后残留的文件：

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

[agemo]

@Ed_S

如果磁盘可用空间不足，会发生什么样的（希望是）优雅降级故障？肯定会有人触发这条路径的！

对于磁盘可用空间不足的用户，先备份再恢复到全新安装中，作为迁移方案，这样可行吗？

（如果是这样的话，这也是升级到操作系统新 LTS 版本的好时机。Ubuntu 26.04 刚发布不久，26.04.1 预计很快发布。全新安装操作系统可能比尝试原地升级更省心。）

呜呜呜呜 …

正如你所猜到的，我没收到这份备忘录……哎呀！

[agemo]

我对这次数据库升级和空间需求一无所知，起初 PostgreSQL 报错提示空间不足 12GB，应用无法重启。我清理了磁盘，设法释放了大约 6GB 空间，再次运行，但仍然没有成功。

我没有继续折腾，而是直接回滚到备份恢复。

[merefield (Robert)]

你随时可以效仿 @pfaffman，迁移到一台全新的服务器，从头开始安装 PG 18 和最新的 Ubuntu LTS 系统……

[agemo]

谢谢。我将执行一次测试迁移，以确认：

@Ed_S

对于磁盘空间不足的用户，先备份再恢复到全新安装中，能否作为一种迁移方式？

同时我会密切关注此话题。
