我当前使用的 3.5.0.beta7-dev 版本，在 web_only 容器设置中加入 AI 插件后，立即遇到了一个 bootstrap 错误。不包含此插件时，相同的构建可以正常工作。
通过阅读 https://meta.discourse.org/t/upgrade-error-rake-db-migrate-index-on-theme-field-id/278935/7，我怀疑根本原因是（外部）Postgres 服务器 13.20 缺少一个扩展。该服务器具有 hstore, pg_trgm, plpgsql, unaccent 扩展，并且也用于生产环境的 Discourse 安装，该安装使用相同的代码，但尚未包含 AI 插件。
有人能确定 AI 插件所需的 Postgres 扩展吗？ 我在 Discourse AI - Self-Hosted Guide 中找不到此信息。类似的错误帖子，例如 AI Plugin Build Error - 'bundle exec rake db:migrate' failed
