Best guess from here is that you managed to run into some sort of cache-reload bug; those are very sensitive to concurrent operations since you only see them when a shared cache inval event happens at just the wrong time. I would recommend an update to 8.4.4 since we did stomp two or three critters of that ilk in the last few months, but I can't really guarantee that we found the one that bit you. While you're at it, please try to make sure you install a non-symbol- stripped version of 8.4.4. If it does happen again, at least you'll be prepared to collect more data. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
