Bob,
PostgreSQL is under the BSD license, which allows anyone to bundle software into a proprietary package with the only requirement being that they provide proper attribution. So Red Hat is allowed to take a PG download and sell it for $2300. So are you for that matter.
They don't own PG in anyway more than you or I. So there's no worry whatsoever that the Red Hat DB endangers the freedom of PG.
That being said, for clients who are afraid of free software, it's nice to tell them that they can spend $2300 and get a lower version of what you can download for free. They get the feeling that there's someone accountable for what they're using. We have a couple of clients who might buy RH DB because of this.
So, in a weird way, RH-DB is actually a service. At least for shops with clients that are initially afraid of OSS.
