Doc: add comment about bug fixed in back branches as of 3f7323cbb. While the bug I just fixed in the back branches doesn't exist in HEAD, the requirement that MULTIEXPR SubPlans not share output parameters still does. Add a comment to memorialize that, because perhaps it could be an issue again s

pgsql: Be more careful to avoid including system headers after perl.h
