While this function works for most cases, there is no guarantee that it
will work for nested map/array/struct, because toString() is not required to be
implemented correctly for Objects in hive.
The preferred way would be to use
ObjectInspectorUtils/ObjectInspectorConvertors to copy/convert <Object,
ObjectInspector> to "Standard Object", and then convert to JDBC objects.

Can we change the name to serializeField (here and in LazySimpleSerDe)?
