Postgresql OpenErp服务器错误

我是新来的。我可以登录了。我试过gunicorp，现在无法登录

请告知可能出现的问题

基本上，您应该仔细检查数据库配置

数据库级错误指出，用于连接PostgreSQL的“vishal”用户不存在。可能您在测试gunicorn部署时更改了db_用户配置，或者您在以前使用另一个系统用户时尝试以“vishal”系统用户身份运行OpenERP。

只需创建一个新角色即可解决此问题。openerp文档（安装手册）对其进行了非常清楚的解释。只需在控制台中键入以下命令，例如：sudo su-postgres Code:createuser--createdb--username postgres--no createrole--no superuser--pwprompt openerp为新角色输入密码：*********************
