Hi, I've the need to persist a the result of an index_getnext() in a tuple slot. I don't want to unneccessarily duplicate the tuple data itself, so I'd like to use ExecStoreTuple(buffer = real_buffer) notion. But since the next index_getnext()/index_endscan() will overwrite/release the heaptuple I need to copy the HeapTupleData(). It'd be rather useful to be able to do ExecStoreTuple(tuple, slot, some_buffer, true), i.e. hav ethe HeapTupleData struct freed *and* the buffer pinned. There's an Assert preventing that though.
