-----------------------------------------------------------------
Agreed. Such queries are currently giving the wrong results.
To fix it, I plan to implement the {{FILTER (WHERE condition)}} clause (i.e.
observe {{AggregateCall.filterArg}}) in {{AggregateNode}} (i.e. the
{{Aggregate}} relational operator as implemented inside the {{Interpreter}})
and this will also fix it for {{BindableAggregate}}.

> BindableAggregate doesn't properly filter aggregates like SUM(cnt)
> FILTER(WHERE foo = 'bar'). It seems to be ignoring the filter completely.
