Thank you for pointing that out! I will look into fixing that some
time this week. If we run without assertions the query still fails
with this error because zedstoream_tuple_tid_valid incorrectly reports
the TID as valid:

Agreed. I think it should match the behavior of heap as closely as
possible.
