    'column':
        The column object or string identifier.
    'length':
        MySQL will only index the first N characters if this is

        You can create an index based on an expression, e.g.,
        'lower(column)'.  This can either be a string or a sqlbuilder
        expression.

    Further keys may be added to the column specs in the future.

    a UNIQUE index is created.
