Evidently you had corruption in the pg_operator catalog. If you were
lucky, a REINDEX of pg_operator might have fixed it, but unless you kept
a physical copy of the corrupted database there's no way to investigate
further now.
8.2.4 is extremely out of date btw, you should be using 8.2.17 or
something close to that.
