I have a decision to make whether to use PostgreSQL or MySQL Innodb in my Drupal installation. I have learned that, contrary to common belief, and unlike PostgreSQL, Innodb is not totally ACID compliant. (See http://www.wikivs.com/wiki/MySQL_vs_PostgreSQL#MySQL:InnoDB and the end of post at http://bugs.mysql.com/bug.php?id=62209). What would this non ACID compliance mean for site reliability when used for Drupal?
