我试图安装postgresql 9.3在我的Ubuntu的清醒机器。 问题是运行apt-get install postgresql-9.3时出现这个错误

看来9.1包中有一个bug ，但是应该修复。
正如链接线程所示，问题可以通过运行来解决：
update-alternatives --remove postmaster.1.gz /usr/share/postgresql/9.1/man/man1/postmaster.1.gz
然后重新安装postgresql-9.1：
apt-get install -f apt-get install --reinstall postgresql-9.1
