Blog software worth to check

As decided already in February, 2007, on an association's meeting, Wikivoyage intends to build up a platform for individual personal travel reports. For long time, this old idea has been out of focus due to more important development tasks, but in recent time de:User:Der Reisende and de:User:Hansm have digged it out, again. Currently (autum 2009), we are testing several blog software and try to figure out which one would best meet our requirement.

From the technical point of view, there is actually only one, but big, limitation: It must support PostgreSQL.

Software in question

 * Wordpress - probably the best known blog software, but unfortunately, developers are not willed to support PG. There are several attempts by single developers to migrate to PG, but even minor version upgrades make crash everything. - No option.
 * Serendipity - Simple, easy to use, but too many dirty shortcuts in the codebase. Still an option, but not first choice.
 * Movable Type - Highly configurable, infinitely many features, but administration seems to be everything but easy. CGI PERL scripts. Developed since 2000. Seems to be very reliable, although many former users have switched over to Wordpress. Unfortunably no UTF-8 URls. Strange "translations" into strict ASCII, instead. Not in first choice.
 * Drupal - Actualy a CMS, so some kind of overkill. In end of 2008, there have been thoughts on stopping PG support.
 * Habari - PG supported, Unicode, even in URLs, is supported. This holds at least for the current (2009-10) developer version.
 * LifeType - PG support in question.
 * Typo - Ruby!
 * DotClear

General

 * http://www.weblogmatrix.org/ - Overview and comparsion of "all" blog software. But they really have listed many.

Movable Type

 * Introduction into templates - nifty stuff, but essential.
 * As explained in the MT forum, UTF-8 URLs are not possible with MT. Unexpected, but seems to be true. Big drawback.
