This change makes sense. The patch looks good to me. I'll cancel the vote
due to this reason. Thanks!

> MySQL InnoDB allows the size of a single column for an index key up to 767
> bytes by default. For a TEXT or VARCHAR column, a UTF-8 character set and the
> maximum of 3 bytes for each character are assumed. So, the current length of
> COLUMN_NAMES (256) causes an error while starting up occasionally.
