Content management system to build web site with PostgreSql, should it be WordPress

I’m looking for a way to build web site which uses PostgreSql to store web pages and allow users to modify them.

 

Admin user should able to create and changed pages using html editor from browser.

Site runs in Debian Squeeze x64 VPS using Apache. There are  Mono 2.8 and PostgreSql 9.1 applications running in this VPS.

 

There is no PHP installed but it can probably installed if software requires this.

 

CMS should provide nice dark theme for web site so that web designer is not required for this.

 

WordPress PostgreSql plugin page http://wordpress.org/extend/plugins/postgresql-for-wordpress/

states this this plugin is not compatible with latest wordpress.

Also this plugin is not updated for a while.

Joomla! does not run in Postgres DBMS.

Drupal 7 seems to support it but comparing to WordPress Drupal usage is smaller.

 

There are mono ASP.NET applications running in this site so using some ASP.NET CMS seems best.

Latest Orchad does not run in Mono and PostgreSQL.

 

Which software is best for  PostgreSql ?

 

Andrus.
