Since you get a duplicate key violation on inserting a row to that table, there's obviously a row with that id there. Perhaps there's a DELETE trigger or rule on this table that does something unexpected? It is indeed a possibility that this is a corrupted index, but that is not something that happens unless more serious matters have been (or are) at hand, like hardware failures.
