Why use ORDER BY 1 instead of just getting the stats for the subscription we
want to test? Seems a bit more robust to show only that one, so we don't get
unnecessary changes if the test needs to create another subscription or such.

Perhaps worth resetting again and checking that the timestamp is bigger than
the previous timestamp? You can do that with \gset etc.
