I don't see any reason why DML/UPDATE pushdown should depend upon
subquery deparsing or least PHV patch. Combined together they can help
in more cases, but without those patches, we will be able to push-down
more stuff. Probably, we should just restrict push-down only for the
cases when above patches are not needed. That makes reviews easy. Once
those patches get committed, we may add more functionality depending
upon the status of this patch. Does that make sense?
