> Currently, SymbolType has no serializable string representation, because it
> is an extension type. But we find that we still need to serialize the symbol
> type, because symbol literals are used in expressions, e.g. {{EXTRACT(DAY
> FROM DATE '1990-12-01')}}. If we want to serialize this experssion, the DAY
> symbol and type are also need to be serialized.
