Re: Primary key duplicates

It appears that I can select the rows, but not delete or update them.

# select ctid from files where ctid = '(53101,30)';
    ctid
------------
 (53101,30)
(1 row)

# delete from files where ctid = '(53101,30)';
DELETE 0
# update files set fileid = 1000 where ctid = '(53101,30)';
UPDATE 0
#
