we have seen repeatedly that users can be confused about why PostgreSQL is not shutting down even though they requested it. Usually, this is because `log_checkpoints' is not enabled and the final checkpoint is being written, delaying shutdown. As no message besides "shutting down" is written to the server log in this case, we even had users believing the server was hanging and pondering killing it manually.
Wouldn't a better place to write this message be the terminal from which "pg_ctl stop" was invoked, rather than the server log file?
