That looks like a data corruption problem :-(. You might want to check
into whether your disks/filesystems are properly configured to honor
fsync.
Assuming this is the only problem, you're in luck as far as recovery
goes, because pg_toast_2619 is the toast table for pg_statistic, which
means there's no irreplaceable data in there. I'd suggest truncating
pg_statistic (as superuser) and then doing a database-wide ANALYZE to
rebuild the content.
