Description: Can't connect/start database after restart
Details:

Hi,

I have 8.3.1 postgres installed and am facing a very weird problem. I
install the program fine and it works fine. However, once I restart the
computer and try to start the database via command line or pgAdmin3 it gives
me error that i can't connect. It tells me to check the logs but i didn't
find any error besides the connect error message itself. I then have to
uninstall and reinstall all over again... I also have trouble clearing
"hidden" history on previous postgres installations - I cleared up the "my
documents" folders with previous postgres installations but the computer
still warns me whenever i use a previous name.

Thanks,
Alex
