В конце последнего источника я прочитал:
Use PIP
You can connect to port 61315 with a JDBC client such as DbVisualizer. For now, you can use the JDBC driver provided with PIP V0.1. Also, you can go in to the "driver" and experiment with PIP. (Yes, this release of PIP is expert friendly.)

Кроме DbVisualizer
(DB Visualizer isn't open source but it has a free version. For anything but the most basic functionality you need the commercial version and the price on that has continued to ratchet up over and over as time wears on. I understand their need to make money and in a business environment where the pockets are deeper, it's an excellent tool. For individuals who are working open source or hobby programming, you'll probably need to look elsewhere)
есть также SQuirreL SQL Client
(is a graphical Java program that will allow you to view the structure of a JDBC compliant database, browse the data in tables, issue SQL commands etc, see Introduction. The minimum version of Java supported is 1.6.x as of SQuirreL version 3.0. See the Old Versions page for versions of SQuirreL that will work with older versions of Java).
