IIRC, we'd have to do htonl on them, so we'd still end up with
two representations ...

The notices (not notifies) are coming out in the opposite order from
expected. I haven't really thought hard about what's causing that;
it seems odd, because isolationtester isn't supposed to give up waiting
for a session until it's visibly blocked according to pg_locks. Maybe
it needs to recheck for incoming data once more after seeing that?
