Writing blobs to database

[Tim Dudgeon]

Is there any specific support in Groovy (e.g using groovy.sql.Sql) for 
writing large binary objects to the database without dropping down to 
the raw JDBC level? I couldn't find any.

To be more specific, I have an InputStream and want to write it to the 
database (in my case a Postgres bytea column). And data MUST be 
streamed, not materialized as a byte array.

Thanks
Tim
