It seems like there's no up to date information on using PostgreSQL with TestStand.
I've seen and tried the stuff here:

Using the versions that specify a connection string, I get:
"Object Reference not set to an instance of an object"
Following the knowledgebase article I get:

And view data generates errors. I've tried "Database management System" types.
