Fix for bug 3440635: expressions containing correlated subqueries error out
We were deparsing SubPlan clause as "Subplan <subplan name>", which leads
to syntax errors in the pushed query.
It's not trivial to push a SubPlan, and typically it has dependencies with outer
query. So treat SubPlan clause as not-pushable. We anyways don't deparse a SubPlan.
