Postgres-xc不会卸载(停止协调器失败)

Question

我在做一些rails开发，意外地安装了postres，而不是普通的postgres包。我立即去删除postgres-xc，但apt-get不会卸载它。我也尝试过安装普通的postgres，但失败的方式是一样的。

sudo apt-获取删除postgres-xc输出：

我发现它至少是部分卸载，因为如果不使用apt-get -f安装来修复它，我就无法安装其他任何东西。

似乎也是一个众所周知的问题

不管怎么说，我可以手动把它从我的安装中取下来。

修好了。解决方案是dpkg --清除postgres-xc。

对我有效的解决办法是：

1. 修改postgres-xc.presm: sudo /var/lib/dpkg/info/postgres-xc.presm在第一行(#/bin/sh -e)后面添加"exit 0“
2. 然后正常删除: sudo apt-获取删除postgres-xc

(我在：https://bugs.launchpad.net/ubuntu/+source/postgres-xc/+bug/1084849找到了这个解决方案)
