cron issues a warning under PostgreSQL

Hello,

I know there is a patch pending review for PostgreSQL. But without this patch, I found this error during cron.php:

user warning: query: SELECT n.title, n.nid, n.type, s.reminder_email, s.forwarding_email, e.event_start AS event_start, e.timezone FROM node n INNER JOIN signup s ON s.nid = n.nid INNER JOIN event e ON n.nid = e.nid INNER JOIN event_timezones tz ON e.timezone = tz.timezone WHERE (s.send_reminder = 1) AND (n.type = 'formation') AND (('2009-12-30 17:32:14' > ((e.event_start - CASE WHEN tz.is_dst = 1 THEN tz.offset_dst ELSE tz."offset" END) - INTERVAL 's.reminder_days_before days'))) AND (('2009-12-30 17:32:14' <= ((e.event_start - CASE WHEN tz.is_dst = 1 THEN tz.offset_dst ELSE tz."offset" END)))) in /home/html/formalib.com/www/sites/all/modules/signup/includes/cron.inc on line 46.

Okay I will review the patch and see if problem persists.
