How about help posting a better question.

First off, use a descriptive subject.  Notice how I've improved this for
you.

Secondly, always cut/paste exact error messages.  There are some people
who will quickly know exactly what is wrong if they see the whole error
message.

Thirdly, have a look in the PostgreSQL server logs.  If there's nothing
telling there, bump up the authentication/connection debugging in
postgresql.conf and try again.  If you get messages but aren't sure what
they mean, post them to the list.

Fourthly, be more specific.  It would be worthwhile to show the snippit
of code that connects, so people know whether you're using IP sockets are
unix domain sockets.

Fifthly, are you using unix domain sockets or IP sockets?  And are the
appropriate permissions in pg_hba.conf?
