I want to assign an empty value to a property of type NpgsqlTsVector. I couldn't find a better option than assigning the result of the function NpgsqlTsVector.Parse(""), but then I receive the following warning:

CS0618: Method 'NpgsqlTypes.NpgsqlTsVector.Parse(string)' is obsolete: 'Client-side parsing of NpgsqlTsVector is unreliable and cannot fully duplicate the PostgreSQL logic. Use PG functions instead (e.g. to_tsvector)'

How can I get an empty value for the NpgsqlTsVector type?
