Repair problems with the result of lookup_rowtype_tupdesc() possibly being
discarded by cache flush while still in use. This is a minimal patch that
just copies the tupdesc anywhere it could be needed across a flush. Applied
to back branches only; Neil Conway is working on a better long-term solution
for HEAD.
