Here's the xmin/xmax/ctid for three problematic records:
prodpublic=# select xmin,xmax,ctid from items_extended where id in
('34537ed90d7546d78f2c172fc8eed687', '3e1d99b7124742b7aaf2f869f7637b0e',
'499b464f141a48619c5ce0475cbe9150');
xmin | xmax | ctid
-----------+-----------+------------
262232659 | 308810030 | (689496,3)
262629744 | 308810034 | (692765,1)
262643188 | 308810035 | (692920,9)
(3 rows)
I have not yet run pg_resetxlog.
Thanks,
