我根本不明白发生了什么。
sudo apt-get remove postgresql
结果是：

Setting up postgresql-9.1 (9.1.10-0ubuntu13.04) ...
* Starting PostgreSQL 9.1 database server * The PostgreSQL server failed to start. Please check the log output:

我的意思是，为什么要尝试启动服务器。正确，我是一个unix新手和一个巨大的postgres新手，请耐心等待，但是在我尝试卸载服务器时随机启动服务器似乎太随机了。只是不明白。
如何完全完全卸载postgresql？
您的第一次安装不确定，这会给您带来麻烦：
sudo dpkg --purge postgresql-9.1
现在，您可以重新安装该软件包：
sudo apt-get -f install
sudo apt-get install postgresql-9.1
