This is a bit hard to believe, and your log extract certainly doesn't
provide any evidence to support the statement. Could we see a complete
self-contained test case?

That only suggests a new incoming connection, which seems probably
unrelated. However, if that new connection is what's going to examine
pg_attribute, maybe the issue is that it's looking before the ALTER has
committed?
