遗憾的是，尝试加载备份未能成功——数据库似乎在某种程度上发生了分歧。我将尝试从容器中提取 /etc/passwd，尽管当容器未运行时，这会带来很多麻烦。
是无法恢复还是无法将其传输到服务器进行恢复？
无法恢复。我可以在全新安装上再试一次，但我在导入器停止运行之前看到的日志提到了字段不匹配。这是一个旧的……我想是 2.9.x 实例？我手边没有笔记。
为了记录在案，我们的一位聪明人找到了 rsync 容器所需正确权限的方法，以便 PostgreSQL 能够运行：
rsync -rog --delete --perms --numeric-ids root@x.x.x.x:/var/discourse/ /var/discourse

running into a problem with rsync all seemed to go well. nit will not rebuild? in part looks like a problem with ports maybe?

Is the server running locally and accepting connections on that socket?

这似乎奏效了。并显示应用程序正在运行，但无法从网络访问。
会不会是还没有从域名服务器连接？
注意：。我想我找到了。可能需要等待 24 到 72 小时 IP 地址更改才能完全生效。
这是我收到的连接消息。推测必须等待名称服务器更新。

我只想重申，在使用 rsync 同步到新服务器时，--numeric-ids 是 100% 必需的。否则，rsync 将尝试匹配主机之间的用户名，这将更改 Docker 内部的文件所有权。这会导致你遇到大量错误消息，最终发现第一个失败是 Postgres 拒绝启动，因为它不再拥有它认为应该拥有的文件，然后还会引发大量其他混乱（Redis 将尝试绑定它已在监听的 TCP 端口，猫狗同居等），使得诊断问题变得困难。
另外，Discourse 制作的、用于在 Discourse 完全控制的 Docker 容器内运行的实际备份 可能无法正常工作，并且显然存在可以追溯到 数年 的、似乎未得到解决的故障，这让我感到非常恐惧，这也是我选择 rsync 来迁移到新硬件的原因。Rsync 成功完成了任务，现在它运行在一个带有每小时快照的镜像 ZFS 文件系统上，并且每天进行远程备份，这很棒……但我确实担心那些认为 Discourse 的自动备份会在灾难中拯救他们而沾沾自喜的管理员，当他们尝试使用备份时，会对着损坏的 SQL 索引以及他们运行了哪些插件而挠头。
我对这个损坏的索引问题感到好奇。如果你有一个损坏的索引，rsync 不会只是将这些错误信息传播到你的新实例吗？备份/恢复至少不会检测到有什么问题吗？
我不太清楚如何最好地修复损坏的索引——我看到 PostgreSQL 文档说：
如果您怀疑用户表上的索引损坏，您可以使用
REINDEX INDEX或REINDEX TABLE简单地重建该索引，或表上的所有索引。
我没有深入研究，所以不能确定，但要么是官方备份方法生成了一个不起作用的 SQL 转储，要么是导入它导致了一个本不必是阻碍性的故障，要么是数据库已经损坏多年，但如果通过 rsync 传输，Postgres 仍然可以运行。
理论上，SQL 索引只是为了加快查询速度，对吧？所以，rsync 过的系统可能只是忽略了它，并且在某些细微方面存在一些我们没有注意到的问题。我真的不知道。
其他线程上的讨论表明，某个版本的 Postgres 破坏了东西，而后续版本修复了它，但我不知道具体的技术细节。
我不确定那是否属实，或者是否总是有效。我认为在某个时候，docker 容器内的用户和/或组 ID 发生了变化。不过，我愿意尝试 –numberic-ids。
对于我进行的新服务器迁移，我一直像这样跳过 postgres 文件：
cd /var/discourse
rsync -rav --numeric-ids =old_ip=:/var/discourse/containers/ /var/discourse/containers/
rsync -rav --numeric-ids =old_ip=:/var/discourse/shared/ /var/discourse/shared/ --exclude log --exclude postgres_* --exclude redis_data --exclude log --exclude tmp --exclude state
并在新机器上恢复备份。
是的。损坏的索引问题可能是一个真正的麻烦。不过，我很久没见过一个了。
是的，但是（我认为）它们也看到事物是唯一的，并且损坏的索引允许你拥有多个具有本应是唯一值的记录。这对于跟踪链接点击之类的东西来说，如果错了也不是特别关键。
我认为我比你更关注这个问题，而上述内容大致总结了我的理解。
也许问题出在 PG12 上？这可以解释为什么我很久没遇到这个问题了，但我不能假装我确切地记得，如果我曾经确定的话。

是否有已知的修复此问题的魔法咒语，即使是以一种通用的方式？比如运行 ./launcher enter app 然后执行 这个特定命令，它就会重建所有的数据库索引，无论是否需要？
Discourse 令人惊叹和可怕之处在于，几乎总有一些神秘的魔法可以解决几乎所有问题，但有时很难找到这些知识。 
（另外，是的，我猜这可能并不总是有效，所以我应该少说点……但将文件所有权映射到新主机服务器上的任何内容都只能靠运气，所以你最好在 rsync 时赌一把 Discourse 镜像仍然具有相同的用户 ID 号。）
你可以
./launcher enter app
sudo su - postgres
psql
然后，（编辑：我查了一下，这似乎是实际的命令）
REINDEX CONCURRENTLY DATABASE discourse;
这将尝试重建它们，如果成功，你就没问题了。如果失败，你需要去删除那些有重复ID的东西。这比较复杂。

这更复杂。
主啊，这真的应验了！
我尝试了一下。请注意，我们的 Discourse 实例导入了大约 15-20 年的邮件列表存档。所以有很多旧帖子看起来像这样……
……你会在其中看到大量的链接，以及邮件回复，这些回复会引用整个前一封邮件，重复这些链接，还有一些邮件签名链接到不相关的项目，等等。
所以，在某个时候，topic_links 表出了问题，开始为它已经拥有的链接创建新行：
所以可能会有一行像这样：
69534 | 18675 | 86333 | 6631 | http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org | lists.libsdl.org | f | | 2017-03-26 12:13:06.365742 | 2017-03-26 12:13:06.365742 | f | 0 | | SDL Info Page | 2017-03-26 13:18:08.491592 | f |
该行创建于 2017 年。但后来我在所有这些帖子中发现数百个重复项，系统在 2024 年又添加了重复的行，id 值比原来的高出 200000。
所以有很多需要清理。
基本上，我会等待重新索引失败，看看它吐出了什么，找到重复行的 ID，然后调整 URL 字符串以不再重复……看起来系统已经通过在字符串中半随机地插入 ** 来处理这个问题了。我也这么做了。我不敢直接删除这些行，因为我不知道这些行在其他地方有什么引用。
它似乎只是一小部分主题，可能是同一主题的不同帖子，因为我一遍又一遍地修复同一小部分 URL。这很乏味，我不推荐这样做。 我可能应该找到一种自动化方法。
还值得注意的是，REINDEX 上的“CONCURRENTLY”选项会构建一个临时索引（在名称后附加 _ccnew* 字符串），如果过程失败，它会保留在那里。如果你打算使用 CONCURRENTLY 并需要清理很多东西，那么在你清理完所有东西时，预计会删除大量临时索引。（另外，如果你像我一样，从未直接使用过 Postgres，也请注意，在 REINDEX 命令可以使用之前，我必须在开始时发出一个 \\connect discourse; 命令。）
我仍在进行这项工作；它似乎并没有让情况变得更糟，所以我将继续努力。
这更像是敷衍了事，而不是真正的帮助，但这里有几个想法。
首先，既然您知道哪个索引已损坏，您可以只重新索引该索引，而不是数据库中的所有索引。您可以向 https://ask.discourse.com/ 寻求有关如何执行此操作的提示。
Corrupt indexes in PG12, how do I fix? - #11 by sam 也有一些提示。
由于您不太关心此链接跟踪（我猜反正已经创建了一个新的），因此删除重复项即可。
应该有一种方法可以执行查询来查找重复项，以便您可以一次性删除它们。
我已经完成了这项工作，Postgres（以及 Discourse！）似乎都很满意。
我手动清理了它们，并根据需要使用 ** 模式使 URL 唯一。这可能只是一个无害的缓存，我可以删除重复项，但我不想冒险。
在我的例子中，只有一个索引，所以重建所有索引可能有点过度，但说实话，我感觉好多了，因为我知道我抓住了所有东西。
在几次重建失败的运行之后，每次运行大约需要 30 秒并报告一个问题，这是我的 SQL 魔术，可以立即获得问题项目的完整列表：
discourse=# select topic_id, post_id, url, COUNT(*) from topic_links GROUP BY topic_id, post_id, url HAVING COUNT(*) > 1 order by topic_id, post_id;
topic_id | post_id | url | count
----------+---------+-------------------------------------------------------+-------
19200 | 88461 | http://hg.libsdl.org/SDL/rev/**533131e24aeb | 2
19207 | 88521 | http://hg.libsdl.org/SDL/rev/44a2e00e7c66 | 2
19255 | 88683 | http://lists.libsdl.org/__listinfo.cgi/sdl-libsdl.org | 2
19255 | 88683 | http://lists.libsdl.org/**listinfo.cgi/sdl-libsdl.org | 2
19523 | 90003 | http://twitter.com/Ironcode_Gaming | 2
(5 rows)
（此查询中剩余 5 个有问题项，仅作示例。）
然后我会查看每个帖子，看看有什么以及如何修复：
select * from topic_links where topic_id=19255 and post_id=88683
然后修复其中一个：
update public.topic_links set url='http://lists.libsdl.org/__listinfo.cgi/**sdl-libsdl.org' where id=275100;
直到我把所有需要修复的东西都修完。
我可能可以用一些内部连接魔术（或者一点 Ruby）在一个查询中完成所有这些工作，但我不是专家，而且手动完成这项工作花费的时间并不是几个小时。但说实话，这确实很繁琐。
然后我运行了 REINDEX DATABASE discourse;，没有 CONCURRENTLY，只是为了简单起见，删除了我之前遗漏的几个 ccnew* 索引，然后我就搞定了。
网站一直在线，没有停机时间。
无论这是否必要，我绝对觉得我的数据现在更安全了，而且我不会走向某个未宣布的未来灾难。
感谢您给我指明了方向来解决这个问题，@pfaffman！
