问题是 apt.postgresql.org 的 precise-pgdg postgresql 包与 raring 兼容，但 logrotate 除外。Logrotate 3.8 更改了其配置文件，postgresql-9.2 将坚持要求您的 logrotate 版本相对于您的 postgresql 版本没有错误。解决此问题的一种方法是在安装 postgresql-9.2 时删除 logrotate。
一个可能的解决方法是安装 precise 的 logrotate（3.8 之前的版本）。这应该可以让 postgresql-9.2 和 rabbitmq 都满意。
我们正在考虑为 apt.postgresql.org 寻找一种解决方法，但到目前为止，还没有人想出一个不需要太多魔法的解决方案。（我们不会支持 apt.postgresql.org 上的 raring 作为单独的发行版，因为它不是 LTS 版本。）
