Was this a transient error, or repeatable?
If it was transient, it's probably a recently-fixed issue:

This seems unrelated. Can you repeat this one? If so, try REINDEX'ing
that index and see if the problem goes away.
It'd be worth your while to update to 9.0.5 --- we fixed a fair number
of potential data-corruption issues since January.
