Hi,
This issue does occasionally happen in CI, as e.g. noted in this thread:

My problem with this approach is that the whole cleanup lock is hugely
misleading as-is. As I noted in
https://www.postgresql.org/message-id/20220817193032.z35vdjhpzkgldrd3%40awork3.anarazel.de
we take the cleanup lock *after* re-initializing the page. Thereby
completely breaking the properties that a cleanup lock normally tries to
guarantee.
Even if that were to achieve something useful (doubtful in this case),
it'd need a huge comment explaining what's going on.
Greetings,
Andres Freund
