EXTRACT starts at 0==Sunday while TO_CHAR starts at 1==Sunday. A suggestion for two documentation notes is attached as a patch to current CVS HEAD. -- Greetings from Troels Arvin, Copenhagen, Denmark Attachments:^ permalink raw reply [nested|flat] 2+ messages in threadpgsql-day-of-week-docs.patch (text/x-patch, 1.2K) download
