I'm seeing two sets of shutdown messages, and apparently a second
shutdown checkpoint being forced, during a normal database stop:

2007-06-30 14:21:00 EDT 9644 LOG:  received smart shutdown request
2007-06-30 14:21:00 EDT 9647 LOG:  shutting down
2007-06-30 14:21:00 EDT 9647 LOG:  checkpoint starting: shutdown immediate
2007-06-30 14:21:00 EDT 9647 LOG:  checkpoint complete: wrote 23 buffers (0.6%); 0 transaction log file(s) added, 0
removed,0 recycled; write=0.003 s, sync=0.178 s, total=0.237 s

2007-06-30 14:21:01 EDT 9655 LOG:  database system is shut down

I haven't looked for the cause yet but I suspect it's got something to
do with this patch:
http://archives.postgresql.org/pgsql-committers/2007-06/msg00285.php
Either that or somebody else broke it recently.
        regards, tom lane
