在处理时有错误发生:
postgresql-9.1
postgresql-client-9.1
E: Sub-process /usr/bin/dpkg returned an error code (1)
使用下面的命令:
sudo rm -r /var/lib/dpkg/info/postgresq*
然后是
sudo apt-get autoremove postgresql*
最后可以看到:
dpkg:警告:files list file for package 'postgresql-9.1' missing; assuming package has no files currently installed
dpkg:警告:files list file for package 'postgresql-client-9.1' missing; assuming package has no files currently installed

其实感觉是第一个命令删除了dpkg关于postgresql的元数据信息,然后使用autoremove命令的时候,dpkg以为postgresql没有安装,然后提示卸载成功了。
