Yes. The main complaint here is not about the existence of the message
but about the fact that it looks like it's reporting a failure. I would
vote for removing it if it's not simple to fix that problem.
Even if we fix that, though, I think it is reasonable to downgrade it to
DEBUG1. We did that already for other standard background processes such
as the autovac launcher, and it's not apparent to me why the logrep
launcher should be chattier. Now, *unexpected* starts or stops should
certainly deserve a higher log rating ... but the general rule ought to be
that totally-expected behavior does not deserve a log entry by default.
