A good place to get help with that is actually the IRC channel (#postgresql on chat.freenode.net, or http://webchat.freenode.net for the web interface - note that currently you need to register a nickname, see http://freenode.net/kb/answer/registration because of some annoying spammers, but we can help you with that if you just go ahead and try and join the channel anyway).
