Well, if the problem is indeed in pg_statistic, it'll be easy to repair
(think TRUNCATE...). Have you turned up the logging level to find out?
BTW, please don't do anything to try to correct the problem until we're
pretty sure we understand how this happened --- we might ask you for
more info. AFAICS this isn't having any bad effects except for bleats
in your log file, so you can wait.
