撇开两者的其他方面，首先是要让它们跑起来， MySQL + PhpMyAdmin 一装， 不看入门教程就把基本的环境搭好了。 而postgresql呢， 我一个学计算机， 第一次配好竟然累计用了差不多5个小时， 关键是找不到很好的入门资料，官方的安装指导毫无实用价值，其他资料也少有击中要害的。 引入了psql， 就该强调一下;运行一个命令，提示信息寥寥数语， 也不确定结果如何; 显示所有数据库， 搜了半天才找到; pgAdmin 3 是需要图形界面的， web的管理软件有没有？
等等等等， pg对第一次的使用者来说， 上手不容易啊。
sudo -u postgres psql postgres 进入psql 模式后，按 ? 可查看 psql 命令， 要执行命令别忘了加分号; 下面列一些典型的命令：
显示所有数据库
mysql : show databases
psql : l 或者l+
使用某数据库
mysql : use xx
psql : c xx
显示数据库表
mysql : show tables
psql : dt
