Particularly since the "box" their own product comes out of is "compiled from CVS checkout". Their argument seems to be that people can learn how to drive CVS and to compile software under active development, but can't read the manual that comes with Postgres (and a release of Postgres well over a year old, at that). I didn't get any further in reading the claims, because it's obviously nothing more than a marketing effort using the principle that deriding everyone else will make them look better. Whether they have a good product is another question entirely. A -- Andrew Sullivan ajs@commandprompt.com +1 503 667 4564 x104 http://www.commandprompt.com/
