I have been looking at all the code surrounding pg_receivewal and
pg_recvlogical and those are indeed the two only places where we print
a message in non-verbose mode even if those are not explicit errors.
pg_recvlogical does not show up any messages when it is signaled or
when it receives SIGINT or reaches the end of LSN position. I don't
think that this is worth complicating the code for, just noticed the
inconsistency on the way.

Perhaps a committer will care about that. Or not. For now I am just
adding that in the CF.
