Extending Pear DB class. Is it possible?

Hi all, I'd like to extend the standard Pear DB class, but there is something a bit curly about it. PHP lets me create a class like: class mydb extends DB { functions etc. } however the new class mydb will not include all the functions. I think it is only including all the functions defined in the 'common.php' file. The 'mydb' class above won't, for example, have the 'query' function, even after successfully connecting to a database. Anyone know how to go about extending the Pear DB class? . . Ross Honniball.
