A client has an existing Heroku Connect integration.

A file storage system needs to be added to the Heroku Connect mapping to sync binary files.

Heroku Connect does not support binary files: therefore migration must be done using another method

A column oftype Binary String must be added manually to the Heroku Postgres table and amend Attachments before binary transfer can be enabled.

An additional object mapping must be added for the Attachments table in Heroku Connect.
