Postgresql error

Hello,

I successfully dumped the database in postgresql. Now I want to connect
my rails application to the postgresql database, able to start the
server, but I am getting this error when I browse the application from
the browser.

script/server
=> Booting WEBrick
=> Rails 2.3.5 application starting on http://0.0.0.0:3000
