Hi,
Another good CMS, IMHO, is drupal (http://drupal.org/). It works well
with PostgreSQL, and we use it successfully at http://www.PostgreSQLFr.org/.
It's stable and maintained, the dev team releases new versions often,
and there are a lot of pluggable modules (
http://drupal.org/project/Modules) to enhace it and make it suitable for
your needs.
There are also many themes available (http://drupal.org/project/Themes)
for you to have it look like you want really quickly.
It supports many languages and has a lot of great features I couldn't
write down on this list, since there are so much, just take a look at
it: http://drupal.org/features
I think drupal is defenitely a solution you have to consider.
Cheers,
PS: do not cross-post
