Rails - Mar 2006 - Hieraki2 status quiestion and postgres schema

Hi,

I am trying to figure out the status of Hieraki project. It seems  
that the
software in use in manuals.rubyonrails.com is old and the new(er)  
version
is quite different. Is this correct? I am somehow confused because in  
seems
that the project wiki/track is under "spam attack" ( http:// 
www.hieraki.org/trac/timeline ).

Also it seems that there is only mysql schema for the current  
release. I''ve
ported it to postgres and it seems to work well. Are there interest  
in this
"contribution"?

Thank you in advance,
