问题描述
我正在使用Ruby和Postgres设置VPS。在我的本地机器上，我安装了postgresql 9.2.3(客户端和服务器)，因此想在我的VPS上安装它。按照此博客文章http://hendrelouw73.wordpress.com/2012/11/14/how-to-install-postgresql-9-1-on-ubuntu-12-10-linux/for的说明在ubuntu上安装postgres(唯一的区别是我尝试安装9.2.3。他安装了9.1)，我做了以下操作
sudo apt-get install postgresql-9.2.3
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package postgresql-9.2.3
E: Couldn't find any package by regex 'postgresql-9.2.3'
但是，如您所见，它找不到软件包postgresql-9.2.3。但是，我已经在本地计算机上安装了该软件包(我使用Homebrew在Mac上安装了该软件包)。
您能帮助我了解我在做什么错吗？
更新我还尝试安装它，最后像下面看到的那样离开’3’，但是您看不到它没有用。
sudo apt-get install postgresql-9.2
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package postgresql-9.2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'postgresql-9.2' has no installation candidate

最佳办法
在Ubuntu官方存储库中，仅PostgreSQL 9.1可用。这就是为什么找不到它的原因。
为了使用apt在您的VPS中获得PostgreSQL v9.2，您应该遵循Ubuntu的官方PostgreSQL程序here
它包括将PostgreSQL官方存储库添加为您的存储库源之一
-
创建文件
/etc/apt/sources.list.d/pgdg.list -
插入此行
deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main -
导入存储库签名密钥
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - -
刷新您的存储库缓存
sudo apt-get update
现在，您只需做sudo apt-get install postgresql-9.2
次佳办法
您能够使用不同的存储库在不同的操作系统上安装postgresql-9.2.3的事实并不重要。
如果使用Web或通过apt查询Ubuntu repositories，则会注意到，quantal附带的版本是9.1。
之所以无法提供定量的postgresql-9.2.3的确切原因，是因为它在冻结时尚未在发布的发行版中接受。
要在Ubuntu中使用postgresql-9.2.3，您需要自己编译。有几种方法，例如使用checkinstall或fpm向后移植或打包上游发行版。
