Splunk DB Connect 2: Why am I getting "The driver class org.postgresql.Driver is not found" trying to validate my Postgres connection?

[jwidhalm]

Setting up a postgres connection and when validating my connection, I received the following error message:

The driver class org.postgresql.Driver is not found, please check if the driver library is installed properly.

I am running this on a Mac and I have trolled through the configuration for Splunk and Postgres on Mac for this on this one and cannot find the any reference for this particular problem. I do see the postgres .jar file () residing in the App folder (/Applications/Splunk/etc/apps/dbx/bin/lib/postgresql-9.0-801.jdbc3.jar)

Any suggestions would be appreciated.

Splunk version 6.2.5, Mac OS 10.10.5, DB Connect v2 version 2.0.4, and RPC Service is UP.
