Auth library for PostgreSQL database

[eluser]kamik[/eluser]
there is something like this:
$sql = "CREATE TABLE `aurole` (`id` int(11) NOT NULL auto_increment,`name` varchar(50) default NULL,PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=utf8";

$this->db->query($sql);

I am not so familiar with MySQL to rewriteing this MySQLs SQLs, there are many others for create tables, selects and etc. In some other libraries I saw that in requirements was MySQL, so I thing that it is the same like this. I am looking good simple Auth library where do not matter on kind of database like you posted. There is many of them, but nothing looks good and when it looks good, there are MySQL commands ... :-(.
