   I understand your request.
   > The implementations for create_name and canonical_name almost fit this 
need but scalar values are surrounded by their type which cannot be parsed by 
sql-parser.
   > E.G col1 = 1 becomes col1 = Int32(1)
   
   It caused here format witg `Debug` model.

   I forget the reason I don't change it to `Display` model. So I not sure it's 
good to change here to solve your question or not.
   
   May be we can ask  @alamb . Thanks 😊
