Updated. In this configuration, in some situations walsender processes
may already have been terminated by the time of fast shutdown.
And in this case, the fast shutdown will be successful, but it will not
be the reason for walsender termination and the logs will be different.
Decided to leave the new shutdown test case, but not check the logs in it.
