MySQLism: use TEXT values and not VARCHAR(255)

When inserting TEXT into a VARCHAR(255), MySQL trims the value to the first 255 characters. PostgreSQL complains and returns an error, which the correct behavior.

Example, in the aggregator module, link is a 255 varchar and we try to insert a longer text.

INSERT INTO aggregator_item (fid, title, link, author, description, timestamp, guid) VALUES (14, 'Dette : l''inté rêt de l''UE est de sauver les meubles', 'http://rss.nouvelobs.com/c/32262/f/437880/s/907f82f/l/0Ltempsreel0Bnouvelobs0N0Cactualites0Ceconomie0Cfinance0 Iet0Imarches0C20A10A0A20A80BOBS63130Cdette0I0Ilinteret0Ide0Ilue0Iest0Ide0Isauver0Iles0Imeubles0Bhtml0Didfx0FRSS0Ieconomie0Gxtor0FRSS0E27/story01.htm', ' ', 'Interview L''économiste Denis Clerc décrypte la chute de l''euro, des bourses mondiales et la faillite possible de la Grèce.

The solution is to use a TEXT and not a VARCHAR(255) when you plan to insert a long text.
