The connection properties that are unique to PostgreSQL are the URL, Driver, User ID, and Password.
They must be exactly as follows:

(where hostname is your IP address, port is an optional port # (default is 5432), and databasename is the database)
JDBC Driver - PostgreSQL (org.postgresql.Driver)
User ID - Any valid user ID
