push_child_plan/pop_child_plan didn't bother to adjust the "ancestors" list of parent plan nodes when descending to a child plan node. I think this was okay when it was written, but it's not okay in the presence of LATERAL references, since a subplan node could easily be returning a LATERAL value back up to the same nestloop node that provides the value. Per changed regression test results, the omission led to failure to interpret Param nodes that have perfectly good interpretations.
