I would like to install Koha 3.0 wiht postgresql but the script on the installation is not good Somebody install this and help me?

I suspect you won't find anybody having installed Koha with PostgreSQL. Koha 3 PostgreSQL support is at a very beta stage. A lot of work still has to be done. It would be great to have someone to work on it. -- Frédéric DEMIANS http://www.tamil.fr/u/fdemians.html
