Hi,
      
          After a RC upgrade (.5.4 -> 0.6), can one blindly run the
      mysql.update.sql, or should I adjust it accordingly to the release
      I am upgrading from?   I ask as I tried and it complained:-
      
      root@peon
          /www/roundcube/SQL # mysql -p roundcubemail <
            mysql.update.sql 
          Enter password: 
          ERROR 1091 (42000) at line 7: Can't DROP 'idx'; check that
          column/key exist
      
      Entry in the mysql.update.sql reads:
    
    ALTER TABLE
        `messages`
        DROP INDEX `idx`,
        DROP INDEX `uid`;
    
    
      mysql>
          describe messages;
