gs_preinstall 做了哪些工作？
1、配置环境linux (列如：/etc/sysctl.ctl, /etc/security/limit.conf 等）
2、创建默认用户、组的创建（omm.dbgrp）
3、创建xml文件指定的路径
4、创建互信 （提前创建了可以不用创建）

卸载openGauss
执行卸载
操作步骤
以操作系统用户omm登录数据库主节点。
使用gs_uninstall卸载openGauss。
gs_uninstall --delete-data
或者在openGauss中每个节点执行本地卸载。
gs_uninstall --delete-data -L
[omm@openeuler161 ~]$ gs_uninstall --delete-data
Checking uninstallation.
Successfully checked uninstallation.
Stopping the cluster.
Successfully stopped the cluster.

一键式环境清理--清理环境
在openGauss卸载完成后，如果不需要在环境上重新部署openGauss，可以运行脚本gs_postuninstall对openGauss服务器上环境信息做清理。openGauss环境清理是对环境准备脚本gs_preinstall所做设置的清理。
前提条件
openGauss卸载执行成功。
root用户互信可用。
只能使用root用户执行gs_postuninstall命
操作检查互信
