Tom, I haven't used the ltree module ... I'll take a look at our DB and see. It's possible that this was an index problem as there was a bulk update with indexes in tact, so there would have been a lot of index shuffling, and the db was not shut down since that update.

If the problem went away after a restart, the bogus value could not have been on disk but must have been in a bad in-memory copy of an index page. Which suggests a hardware glitch ... although if you are using contrib/ltree, I recall seeing several bug fixes go by recently that were described as fixing potential ltree-index corruption issues. regards, tom lane ------------------------------------------------------- Click link below if it is SPAM gsw@xxxxxxxxxxxxxxxx "https://mailscanner.globexplorer.com/dspam/dspam.cgi?signatureID=4519aa77100151804284693&user=gsw@xxxxxxxxxxxxxxxx&retrain=spam&template=history&history_page=1"; !DSPAM:4519aa77100151804284693! -------------------------------------------------------
