Jsonb: jbvBinary usage in the convertJsonbValue?

Hi all,

I'm little confused by the *convertJsonbValue* functon at *jsonb_utils.c*
Maybe I misunderstood something, so I need help =)

>>> if (IsAJsonbScalar(val) || val->type == jbvBinary)
>>> convertJsonbScalar(buffer, header, val);

As I can see, the *convertJsonbScalar* function is used for scalar and
binary jsonb values. But this function doesn't handle the jbvBinary type.

>>> switch (scalarVal->type)
>>> case jbvNull:
>>> ...
>>> case jbvString:
>>> ...
>>> case jbvNumeric:
>>> .....
>>> case jbvBool:
>>> .....
>>> default:
>>> elog(ERROR, "invalid jsonb scalar type");

Does this mean, that binary type is incorrect for *convertJsonbValue *? Or
am I missed something?
