Right, I never said that, I was just commenting on your view that the
predominant use-case for SRFs is returning refcounted tupdescs.
You didn't comment on my proposed solution (FreeTupleDesc() iff refcount
== -1). ISTM that we *need* to free the TupleDesc in at least some
cases, in order to defend against the practice of explicitly allocating
the TupleDesc in the per-query context.
