Hi,
I thought I could speed up the installation, so I have written small
install script using InnoSetup. I know that it's not so powerfull, but
for now it could be good enough. I just post it here as attachment.
All you need is to build&install postgres using msys&mingw. Copy this
file and COPYRIGHT in /local/pgsql and start it.
InnoSetup could be found under http://www.jrsoftware.org/isinfo.php

Martin
