Rather than bring back that flag, can we just use isTempOrToastNamespace
within RELATION_IS_OTHER_TEMP?
#define RELATION_IS_OTHER_TEMP(relation) \
((relation)->rd_rel->relpersistence == RELPERSISTENCE_TEMP \
&& !isTempOrToastNamespace((relation)->rd_rel->relnamespace))
(I haven't analyzed the above code very carefully; it's just for
illustration purposes).
