Unfortuately, it would only be laughable until they sued someone (or, more likely, threatened to do) who was selling PosrgreSQL. The problem in such cases is that proving your obvious prior art is an expensive undertaking. The likely path for a targeted "infringer" is just to give up and either pay something to MS or else use some other engine that doesn't "infringe".
