Extra shows if column has attribute AUTO_INCREMENT. Comments shows comment on the
column level. For example:
mysql> show full fields from test;
+-------+---------+-----------+------+-----+---------+----------------+---------------------------------+-------------------+

+-------+---------+-----------+------+-----+---------+----------------+---------------------------------+-------------------+
| id | int(11) | NULL | | PRI | NULL | auto_increment |
select,insert,update,references | this is a comment |
