External DB connection to Redshift via Database Connector App?

Hello,

I have been working with the Database Connector to connect to Mysql successfully, however most data I need is up in a Redshift instance.

I have tried several different variants of the jdbcUrl string and added several drivers to the userlib folder (both redshift and postgres), but cannot get it to work.

i.e.

'jdbc:redshift://my-instance:5439/my_db'

Drivers:

RedshiftJDBC4-no-awssdk-1.2.7.1003.jar

RedshiftJDBC42-no-awssdk-1.2.7.1003.jar

RedshiftJDBC42-1.2.7.1003.jar

Any (or all) of the drivers used with the jdbc:redshift return this Error:

com.mendix.modules.microflowengine.MicroflowException: com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: java.lang.RuntimeException: Failed to get driver instance for jdbcUrl=jdbc:redshift://my-instance.redshift.amazonaws.com:5439/mydb

Advanced stacktrace:
    at com.mendix.modules.microflowengine.MicroflowUtil.processException(MicroflowUtil.java:144)

Also, since Redshift is a fork of Postgres, I tried to trick the system by using the jdbc:postgresql prefix to call the instance. As suggested in the Amazon docs here http://docs.aws.amazon.com/redshift/latest/mgmt/configure-jdbc-connection.html

Used driver: postgresql-42.1.4.jar

'jdbc:postgresql://my-instance:5439/my_db'

Any suggestions how to make this work?
