length value for some classes extending LogicalType.

[Krzysztof Chmielewski]

Hi,
some classes extending LogicalType.java such as VarCharType, BinaryType,
CharType and few others have an optional argument "length". If not
specified, length is set to default value which is 1.

I would like to ask, what are the implications of that? What can happen if
I use the default length value 1 but the actual length of the data will be
bigger than 1?

For example:
RowType.of("col1", new CharType()) <- this will use default length value 1.
