centos安装卸载Postgresql数据库PGSQL10

　　这几天ytkah正在测试Odoo，而Odoo12一定要PGSQL10否则安装数据库的时候会出错，所以就直接安装gpsql10。首先卸载旧版本postgresql

yum remove postgresql*

　　然后开始安装10版本

yum install https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm
yum install postgresql10
yum install postgresql10-server
/usr/pgsql-10/bin/postgresql-10-setup initdb
systemctl enable postgresql-10
systemctl start postgresql-10
su - postgres -c "createuser -s odoo"
