Could it be the result of running an over 3 year old version of
8.2? Try checking the release notes for the last 13 releases and
see if any of the fixes might apply to your situation. I would
certainly upgrade to prevent future problems and data loss. There
are good reasons for all of the point releases for the major
PostgreSQL releases. Maybe someone else can remember details of
a problem such as yours.
Good luck.
Ken
