我正在尝试更新我的gitlab版本。 但是，我正在关注update
我目前在第5步，db migrate命令：
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
运行命令时出现此错误：

因为错误说我试图启用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;"
然后我收到了这个错误：
ERROR: could not open extension control file "/usr/share/postgresql/9.3/extension/pg_trgm.control": Aucun fichier ou dossier de ce type
我也尝试过用户git，我的gitlab用户并得到了同样的错误。
os运行是一个ubuntu 16.04 LTS，一个严格的事情是/ usr / share / postgres中有两个postgres文件夹，9.3和9.5。 在9.5 /扩展名中，存在pg_trgm.control文件。
我能做些什么才能让它发挥作用？
感谢

看起来您必须为PostgreSQL 9.3安装软件包postgresql-contrib，尝试执行以下命令：apt-get install postgresql-contrib，同时还要检查包含apt-cache show postgresql-contrib的软件包的版本。
如果不是9.3，请按照此instruction为Ubuntu添加PostgreSQL存储库并运行apt-get update和apt-get install postgresql-contrib-9.3
