I'm already pretty seriously unhappy about the log-spamming effects of
64da07c41 (default to log_checkpoints=on), and am willing to lay a side
bet that that gets reverted after we have some field experience with it.
This proposal seems far worse from that standpoint. Keep in mind that
our out-of-the-box logging configuration still doesn't have any log
rotation ability, which means that the noisier the server is in normal
operation, the sooner you fill your disk.
