Wordpress does not support anything other than MySQL, which is somewhat unique as far as CMSes go. There seem to be a few Drupal addons that don&#x27;t mix with Postgres, but other than that it should be fine. Same with all others.<p>Generally, if you can, you should consider supporting Postgres in your framework. It&#x27;s a much saner and robuster database from an Ops point of view (replication doesn&#x27;t fail as often) and more flexible from a Dev view (performance is generally more predictable, much wider feature set with document storage &#x2F; PostGIS &#x2F; etc., …).
