The test assumed that advancing WAL would lead to a checkpoint that invalidates the obsolete replication slot. If a checkpoint that started before the WAL switch completes first, the following checkpoint can be skipped as idle, so the expected walsender termination is not logged. Force a CHECKPOINT in a background psql session after advancing WAL, so the slot invalidation is exercised deterministically.
