安装 postgres-xc 和 postgres-xc-client 后，Postgressql 安装中断。我尝试卸载，但无法卸载。活动日志如下：
postgres@ashUbuntu:~$ sudo apt-get remove --purge postgres-xc-client postgres-xc
[sudo] password for postgres:
postgres is not in the sudoers file. This incident will be reported.
尝试添加到 sudo 组但没有帮助。
postgres@ashUbuntu:~$ sudo usermod -a -G sudo postgres
[sudo] password for postgres:
postgres is not in the sudoers file. This incident will be reported.
现在我很困惑，请帮帮我。
@AB 解决方案有效，能够卸载：
ashutosh@ashUbuntu:~$ su ashutosh

ashutosh@ashUbuntu:~$ dpkg --purge postgres-xc
dpkg: error: requested operation requires superuser privilege
ashutosh@ashUbuntu:~$ sudo dpkg --purge postgres-xc

我假设您的用户帐户不是postgres。因此，使用以下方式切换到您的帐户
su - your_user_name
并再次开始卸载
