一、背景

安装postgresql的时候可能由于版本不对或其他问题导致如下报错，无法继续安装也无法卸载

/var/lib/dpkg/info/postgresql-client-12.postinst: 7: .: cannot open /usr/share/postgresql-common/maintscripts-functions: No such file

二、解决

可以在另一个机器上面安装common拷贝文件，这里面直接把文件写出来了，

vim /usr/share/postgresql-common/maintscripts-functions
apt remove postgresql-client-12
# 之后就可以正常使用了

# This file contains common functionality for all postgresql server
# package maintainer scripts.

# arguments: version master package [package]
