I've applied a fix that takes the approach of explicitly testing for
null plancache->raw_parse_tree whereever necessary. There were at least
two places where there was no such test before; I think they are probably
unreachable with an empty query (because no replanning could ever be
needed) but it seems best to be consistent.
