======Localhost missing from Vista HOSTS file======
The PostgreSQL database server needs to be able to resolve the 'localhost' name for it to run. On some Windows Vista installations, the HOSTS file seems to be missing the **localhost** entry (usually it is there, but it seems to be a common problem for it not to be there).

To resolve this problem, find Start -> Programs -> Accessories -> Notepad, and right-click Notepad, and choose **Run as administrator**. Then, choose File -> Open in Notepad, and open **c:\windows\system32\drivers\etc\hosts**. Add a line at the bottom saying:

**127.0.0.1      localhost**

Save the file, and that should resolve the problem.
