troubles with db classes

Hello, I found out the problem at last. The query() method is not implemented in the pgsql.php file. So when I call the query method, it is called but as no implementation is provided nothing happens (and no error or warning is displayed as well). When I try to get count of rows returned I get the real error... Wouldn't it be better to give a descriptive error message when numrows() is called for a handle which is not valid or not full with some data? Stig? thanks, -bd
