I still find that entirely unsafe, particularly for something you
propose to back-patch into stable branches.  Negative refcount does
not prove that the SRF itself hasn't still got a pointer to the tupdesc.

Can't we fix it so that the tupdesc is allocated in the new special
context (at least in the primary code paths), and then no explicit
free is needed?
