DELETE FROM `{PREFIX}post_meta` WHERE meta_key = 'kksr_fingerprint_default'

{PREFIX} is the string $table_prefix defined in wp-config.php; of course be careful in run SQL DELETE, create a table backup and (maybe) execute first a single line deletion to check the result

DELETE FROM `{PREFIX}post_meta` WHERE meta_key = 'kksr_fingerprint_default' LIMIT 1

First, make sure you back up your database. :)

If you're wanting to run a SQL command directly - perhaps using phpMyAdmin - the query would be

DELETE FROM wp_postmeta WHERE meta_key = 'kksr_fingerprint_default'
