我刚在Linux Mint中安装了Odoo，安装过程是正确的。我在安装Postgre时丢失了数据库数据，当我启动openerp-server并加载localhost：8069时，网页显示：“服务器发生内部错误，无法完成您的要求。可能是服务器超载，或是应用程序发生错误。”
在Odoo日志中，错误为：

2014-08-10 11:02:55,941 4924 ERROR ? openerp.addons.bus.bus: Bus.loop error, sleep and retry

OperationalError: fe_sendauth: no password supplied

我如何纠正它，并正确配置Odoo和Postgre之间的数据连接？我是新的这些程序，并感谢详细的一步一步的帮助来解决：）
提前感谢！
