Hello,
There are a couple of things it could be. I would suggest that you take
down the database, start it up with -P? (I think it is -o '-P' it might
be -p '-O' I don't recall) and try and reindex the database itself.
You can also do a vacuuum verbose and see if you get some more errors you
may have a corrupt system index that needs to be reindexed.
Sincerely,
Johsua D. Drake
