Heh, It's worth asking (it's means you are doing your job), but the  
answer for all practical purposes is "it doesn't matter". The  
documentation as stated is incorrect (for one thing, the UUID  
generation request is independent of a database), and performing such  
a check would be needlessly expensive, given the extremely low  
likelihood of collision. And of course if there is a collision, it's  
automatically detected and no data is lost.
