Re: Declarative partitioning grammar

Hi,

If you think in terms of split points, having to alter two partitions 
isn't true, you just add a split point.

Of course, that also alters the "constraints" of the partitions, but I 
think we all agree that the system should maintain those constraints 
automatically, anyway. As such, they don't even have to be visible to 
the DBA.

IMO, better go right to a fully automated approach. Or why would you 
need partition names in such a case?
