SQL Gateway getClob() errors in Redshift and Postgresql

I'm trying to use the EnsLib.SQL.Operation.GenericOperation component in a production to read a column from a Redshift table that is set up as VARCHAR(65535) and am getting the following error.  

An error was received : ERROR #5023: Remote Gateway Error: JDBC Gateway getClob(0,1) errorRemote JDBC error: Cannot convert the column of type VARCHAR to requested type long..

The query I'm using is a simple 'SELECT column_name FROM table_name'.  I've done a little research and it sounds like Redshift doesn't support getClob().  Is there anything I can do to force the gateway to not use getClob() on this Redshift column, or some other work around?  Casting the column in my select statement doesn't work... it seems the getClob() call is done under the hood by the gateway, and I would potentially need some way to override that?  

Thanks,
