After updating Joomla to version 3.2.3 (using MySQL database), the Extensions > Extension Manager > Database > [Fix] shows "Warning: Database is not up to date!"
1 Database Problem Found:
Database schema version (3.2.3-2014-02-20) does not match CMS version (3.2.3).
Probably an error with the database check functionality. When you get the error above, there's probably nothing wrong with your database
Apparently this check will be fixed in the next Joomla version: https://github.com/joomla/joomla-cms/commit/b382d19b2ae5dcb320c56628b237545bbb31b2cd
