Description
"maxlength" is a required keyword argument for a CharField, yet no error is raised if the argument is not provided.
The error produces its effect much later when the SQL code containing "varchar(None)" fails.
It would be better for CharField to raise an exception immediately, so as to simplify debugging.

The model validator catches this.

An alternative would be to create only "varchar" fields (without length defined), as it is supported with at least sqlite and postgresql. That way one could make use of the PostgreSQL unbound varchars - you can for example index them (you can't index text fields).
