我正在尝试将我的 discourse 实例从 2.9.0.beta10 更新到 3.2.0.beta1。
我遇到了类似这样的错误：

--------------------
Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return #<Process::Status: pid 787 exit 1>
Location of failure: /usr/local/lib/ruby/gems/3.2.0/gems/pups-1.1.1/lib/pups/exec_command.rb:117:in `spawn'
exec failed with the params {"cd"=>"$home", "hook"=>"db_migrate", "cmd"=>["su discourse -c 'bundle exec rake db:migrate'"]}
有什么想法是什么问题吗？
我以前更新过我的实例，没有出现错误。
Discourse doctor 没有给我任何线索可以搜索。
上面的消息是指这个 SQL 语句吗？
UPDATE tags t
SET public_topic_count = x.topic_count
FROM (
SELECT COUNT(topics.id) AS topic_count,
tags.id AS tag_id
FROM tags
INNER JOIN topic_tags ON tags.id = topic_tags.tag_id
INNER JOIN topics ON topics.id = topic_tags.topic_id AND topics.deleted_at IS NULL AND topics.archetype != 'private_message'
INNER JOIN categories ON categories.id = topics.category_id AND NOT categories.read_restricted
GROUP BY tags.id
) x
WHERE x.tag_id = t.id
AND x.topic_count <> t.public_topic_count;
因为如果我在数据库中直接运行 SELECT 部分的代码，我不会收到错误。
我看到 db:migrate 作业首先通过 add_column(:tags, :public_topic_count, :integer, {:default=>0, :null=>false}) 添加列。
不知道为什么之后在上面的查询中失败？
