>
> Suppose that {{t (i, j, k)}} is a table that implements
> ProjectableFilterableTable, we execute the query {{select k from t where j =
> 1}}, and {{t}} refuses to evaluate the filter {{j = 1}}.
> We should still push the project to the table. But we need to project the
> extra column, {{j}} needed by the filter, and transform it, because it now
> occurs after the project.
