Confirmed on OS X 10.6, PHP 5.3.2, MySQL 5.1.51, DBAL RC3. Schema-tool always generates a VARCHAR(255) column for cases like this. 1.x used to generate TEXT, which I would assume is the correct behavior with MySQL in this case.

Fixed, the max length of varchars was set to 255.

However this is rather the default value. The maximum value is now 4000, which is the smallest common denominator between all supported vendors (Oracle is that).

In the future we would probably allow arbitrary large sizes here and switch to a CLOB definition automatically if the specifed string length is larger than max length.
