Hah.

It seems to me that this code should silently return if
rd_rel->reltoastrelid == 0; just like in the case of
txn->toast_hash == NULL.  It evidently means that no datum can be
toasted, and therefor no toast replacement is needed.

(As far as I recall, a table cannot go from having a toast table to not
having one.)
