Close yet another race condition in replication slot test code
Buildfarm shows that this test has a further failure mode when a
checkpoint starts earlier than expected, so we detect a "checkpoint
completed" line that's not the one we want. Change the config to try
and prevent this.
Per buildfarm
While at it, update one comment that was forgotten in commit
d18e75664a2f.
