The reason is that gda_data_model_iter_set_at_row() returned FALSE
meaning it could not set the iter at the requested row, which is why
it always returns the same value. The reason it returns FALSE is that
it's not implemented (specifically the i_iter_at_row virtual method is
not implemented). Of course it an iterator can move forward and
backward, there could be a default implementation to move it to a
desired row...
