> Improve vector value validation errors
> --------------------------------------

> Some of the error messages shown when trying to bind a vector column with a
> wrong value are a bit obscure. For example, if we try to write a value with
> the wrong number of dimensions:
> {code}
> createTable("CREATE TABLE %s (pk int primary key, value vector<int, 2>)");
> execute("INSERT INTO %s (pk, value) VALUES (0, ?)", vector(1));
> {code}
> The error is:
> {code}
> java.lang.IndexOutOfBoundsException: Attempted to read 4, but the size is 0
> {code}
> I understand that we cannot provide a lot of information about a
> non-understandable bind value, since we don't even know whether it's a vector
> or something entirely different. But we could try to improve it a bit and
> throw a {{MarshalException}} that will be translated to a
> {{InvalidRequestException}}, and provide generic messages similar to those
> used by collections:
> {code}
> InvalidRequestException: Not enough bytes to read a vector<int, 2>
> {code}
