Declaration of xxx should be compatible with yyy

The notices have to do with a change to the error reporting levels in the index.php file. The errors were always there, but they were previously being suppressed.

The CI3 DB_driver actually does something similar to what you're looking for:

PHP Code:

    public function call_function($function)
    {
        $driver = ($this->dbdriver === 'postgre') ? 'pg_' : $this->dbdriver.'_';

        if (FALSE === strpos($driver, $function))
        {
            $function = $driver.$function;
        }

        if ( ! function_exists($function))
        {
            return ($this->db_debug) ? $this->display_error('db_unsupported_function') : FALSE;
        }

        return (func_num_args() > 1)
            ? call_user_func_array($function, array_slice(func_get_args(), 1))
            : call_user_func($function);
    } 


From this, I would assume that your example would work as expected.
