Hmm, I believe the idea of heap_open is to check that the relation is

backed by a heap that you can read with heap_beginscan+heap_next. At the

moment that includes normal tables, sequences and toast tables. Foreign

tables would not fall into that category.

I don't believe that that definition is documented anyplace; if we
decide that's what we want it to mean, some code comments would be in
order.
