Setting Column Value to the Contents of a file

Use Case:
I’m trying to insert a row of data in which one of the columns is a blob.  I have the blob/binary data saved in a file.

Is there a way I can reference this blob file in my liquibase insert tag?

With 2.0.4, there is now support for specifying a valueBlob or valueClob attribute on the loadData elements that specify the file to load data from.
