I am using Windows 7, so it may not work like that, but it's worth a try. First you need to install a local postgresql server. When this is done, it is quite simple, just right-click on your PostgreSQL connection, and then click “Change Connection”. Here you can choose your local client.
I have to say that I am looking long enough for this on my own. Hope this helps.
And this is my first post, sorry if I did something wrong.
