Ugh.  I supposed that it was okay that 317aba70e etc. didn't touch
outfuncs/readfuncs, but I did not think of
-DWRITE_READ_PARSE_PLAN_TREES.

Perhaps a good hack to deal with that is to make setrefs.c clear
out relid for RTE_SUBQUERY RTEs in those branches.  Then, in the
same way that the rte->function hack doesn't escape the planner,
this one wouldn't either.
