Save multisignature transaction on Postgresql

Hi everyone,
is possible to save the .stxn file and the .params file on a Postgrsql DB? I want to save this two file, after that an account sign it, and retrieve these so another account can sign the file and send to the network.

Thanks :slight_smile:

Can you store them as blobs?

Thank you for your help. At the end I read the insede of the files and store it in json format.
