I agree that we don't need YAGUC here, particularly not one that applies
indiscriminately to all bgworkers.  I'd vote for just decreasing the log
level.  The current coding is appropriate for a facility that's basically
experimental; but as it moves towards being something that would be used
routinely in production, the argument for being noisy in the log gets
weaker and weaker.
