A quick diff of the 3.2 and 3.3 versions of these files shows this table was changed: CREATE TABLE bayes_token ( id int(11) NOT NULL default '0', token char(5) NOT NULL default '', spam_count int(11) NOT NULL default '0', ham_count int(11) NOT NULL default '0', atime int(11) NOT NULL default '0', PRIMARY KEY (id, token), INDEX bayes_token_idx1 (token), <- deleted INDEX bayes_token_idx2 (id, atime) <- renamed idx1 ) TYPE=MyISAM; So token was both a primary key, and an index, which is redundant.
