> 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.
