That's really cool, thanks. Now the next step is to prevent users  
from having to do this at all I think...

We have an updateSchema() method in the XWikiHibernateBaseStore class.

Does anyone know why steps 1) and 5) have to be done for it to work  
with PostGreSQL? Is that something we could add in updateSchema()?

AFAIK the easiest way to change the skin is to log in as admin, edit  
your wiki preferences and under skin, use xwiki10b1.

Thanks for the kind words and thanks for fixing the PostGreSQL issue!  
Lots of users are going to praise you :-)
