Best of luck, the two standard links for this kind of problem are: http://wiki.postgresql.org/wiki/Guide_to_reporting_problems http://wiki.postgresql.org/wiki/SlowQueryQuestions Note that in creating the information needed to report a problem you may well wind up troubleshooting it and fixing it. That's a good thing :)
