> Should not pushdown Filter through Aggregate without group keys

>
> If we are given a query
> SELECT count(x) FROM tbl HAVING false;
> This query should produce an empty set.
> We should not allow a filter to pass through this aggregate. When the
> aggregate has no group by, there is always one implied group (for the whole
> dataset). So if we apply the filter before the aggregate, the implied group
> will still be created. This is not what we want, since the filter should
> produce an empty set.
