> A query such as:
> select (select func(e1)) from g1
> where func is a must pushdown function will fail due to not finding the correlated value e1.  This happens regardless of whether func is from the same source as g1 - because currently the plan will be the same either way (we don't yet see a way to associate the subplan with the g1 source).
