Dear hackers,
(CC: Alexander, who is an original committer)
While reviewing others, I found $SUBJECT.
Initially the tests inserted 2M tuples twice, and 4464fddf improves to use the advance_wal().
However, code comments in the test missed to be updated.
PSA the fix patch.
This exists PG17+, which has the same TAP test.
Best regards,
