Python UDFs with blob column

Hello, I've been recently working with Python UDFs in MonetDB and I've noticed that returning a blob column from an array of python objects is not allowed. A look at the code confirmed  that this feature is not implemented yet: "FIXME: check for byte array/or pickle object to string". I have thus written an implementation of this feature. Could you please tell me how I can submit my code for you to review it and consider to apply it? Thanks. Best regards, Florestan
