Wiki content license

The content of our wiki is licensed per this page:
http://wiki.postgresql.org/wiki/PostgreSQL_wiki:Copyrights

However, from what I can tell, this is only linked once you open the
editor on a page. Thus, as a visitor, you can't see what license
things are available under.

Can we get this into for example the list of links at the bottom of
each page, in some easy way?

if not, we should just link it from
http://wiki.postgresql.org/wiki/PostgreSQL_wiki:About, but having a
direct link is probably better?
