I don't think the tuple packing issue has to do with the tuple
descriptor code.  The tuple descriptors already use allocations of size
sizeof(FormData_pg_attribute) (CreateTemplateTupleDesc), just the memcpy
and memset calls use (potentially) less.  That might have saved a few
bytes for omitting the varlena fields, but I don't think it affects
alignment correctness.  If we, say, added a trailing char field now, the
only thing this code
