Log message:
    Clean up handling of tuple descriptors so that result-tuple descriptors
    allocated by plan nodes are not leaked at end of query.  This doesn't
    really matter for normal queries, but it sure does for queries invoked
    repetitively inside SQL functions.  Clean up some other grotty code
    associated with tupdescs, and fix a few other memory leaks exposed by
    tests with simple SQL functions.
