postgresql - 更新我的gitlab，数据库迁移失败

Question

我正在尝试更新我的 gitlab 版本。虽然，我正在关注这个 update

我目前在第 5 步，db migrate 命令:

sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production

我在运行命令时出现此错误:

== 20160226114608 AddTrigramIndexesForSearching: migrating     ====================

-- execute("SELECT true AS enabled FROM pg_available_extensions WHERE     name = 'pg_trgm' AND installed_version IS NOT NULL;")

正如错误所说，我尝试启用 pg_trgp 扩展，所以我尝试了这个 tutorial .我已经安装了 postgresql-contrib，以 postgres 用户身份登录并运行命令:

psql -d gitlabhq_production -c "CREATE EXTENSION pg_trgm;"

然后我得到了这个错误:

ERROR:  could not open extension control file "/usr/share/postgresql/9.3/extension/pg_trgm.control": Aucun fichier ou dossier de ce type

我也尝试了用户 git，我的 gitlab 用户，但得到了同样的错误。

运行的操作系统是 ubuntu 16.04 LTS，一个重要的事情是/usr/share/postgres 中有两个 postgres 文件夹，9.3 和 9.5。在 9.5/extension 中存在 pg_trgm.control 文件。

我该怎么做才能让它发挥作用？

谢谢

看起来你必须为 PostgreSQL 9.3 安装包 postgresql-contrib，尝试以下命令:apt-get install postgresql-contrib，同时检查版本包含 apt-cache show postgresql-contrib 的包。如果不是9.3，按照这个instruction为 Ubuntu 添加 PostgreSQL 存储库并运行 apt-get update 和 apt-get install postgresql-contrib-9.3
