postgresql登录
1、可通过客户端pgadmin iii直接登录
2、可通过命令行
命令:psql -h 10.10.10.10 -u user -d postgres -p 5570
-h:数据库ip
-u:登录用户
-d:登录的数据库
-p:登录端口
方法:进入postgresql的客户端安装目录(我的安装目录:c:program filespostgresql9.4bin),执行psql命令,其中q表示退出数据库
修改密码
直接执行以下sql即可修改密码
alter user pguser with password 'new password';
补充:postgresql修改密码认证方式
我就废话不多说了,大家还是直接看代码吧~
