We're not talking about representing all CharFields as TEXT, it is about choosing a sane length as the default for the varchar datatype. So if you would not specify max_length, for MySQL it would be varchar(255), for oracle it would be varchar(4000 / bytes_per_char_for NLS_CHARACTERSET) and for PostgreSQL it would be just VARCHAR without a length.
I would like some comments / help for how to compute the size of the string in bytes for Oracle. unless we can opt for using a default length of 255 for all database backends besides postgres.
