我已经设置了一个新数据库来在 PostgreSQL 中安装 Discourse。当我运行 rake db:migrate 时，它​​会创建大部分表，但随后会失败：

-- execute("INSERT INTO archetypes (name_key, created_at, updated_at) VALUES ('poll', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP)")
   -> 0.0009s
-- add_column(:forum_threads, :archetype_id, :integer, {:default=>1, :null=>false})
   -> 0.0209s
==  CreateArchetypes: migrated (0.0424s) ======================================

==  AddMetaDataToForumThreads: migrating ======================================
-- execute("CREATE EXTENSION IF NOT EXISTS hstore")
rake aborted!
An error has occurred, this and all later migrations canceled:

有什么线索吗？

尝试未安装CREATE EXTENSION [...] hstore扩展时，从数据库错误“无法打开扩展控制文件”中出现。hstore

在 Ubuntu 上，您可以通过安装postgresql-contrib包来安装扩展。

sudo apt-get install postgresql-contrib

用户 terryjray 在 Gist 中记录了启用 hstore。

如果您Postgresql在 ubuntu 上有两个安装，例如9.1和9.3

在运行特定于版本的安装之前，您可能需要使用他们的说明添加正确的 postgres 存储库，我将在下面解释它们以防它们消失：

deb http://apt.postgresql.org/pub/repos/apt/ UBUNTU_VERSION_NAME-pgdg main
sudo apt-get install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
apt-get update

（UBUNTU_VERSION_NAME 应替换为 trusty 或任何您的版本名称）

然后您可以使用以下命令hstore分别在每台服务器上安装扩展：

PostgreSQL 9.1：

sudo apt-get install postgresql-contrib-9.1

PostgreSQL 9.3：

sudo apt-get install postgresql-contrib
