Hmm... This broke the SSI patch, which was using rd_istemp to omit
conflict checking where it was set to true. The property I care
about is whether tuples in one backend can be read by an transaction
in a different backend, which I assumed would not be true for
temporary tables. Which of the above would be appropriate for that
use?
