That was the simplification :-) There is an exception for PHP (and also
FOSS exception). If I remember it well, the app must be distributed
under GPL license or PHP license version 3.0 to be able to use the MySQL
for free. As you can see, PHP 5 doesn't contain MySQL extension compiled
in by default, but PHP 4 did. This change may be caused by the change of
MySQL license. You can see it here
http://cz2.php.net/manual/en/ref.mysql.php and here
http://cz2.php.net/manual/en/faq.databases.php#faq.databases.mysql.php5.

Detail MySQL licensing information can be found here
http://www.mysql.com/company/legal/licensing/opensource-license.html and
here http://www.mysql.com/company/legal/licensing/commercial-license.html.

I'm no longer interested in the MySQL licenses because I've already made
my decision. I think that PostgreSQL license is much better (and much
more cleaner) and most people will sleep much better when using
PostgreSQL instead of MySQL ;-)
