Oh, as I was writing a CUBE query today and realized that I forgot to
mention this. And unlike most gripes, like MERGE INTO or CTE's which are
really convenience things, this is key piece of functionality that you
just can't reproduce in Postgres.
That said, there's not the same sense of community when it comes to
Oracle. And how many of you have ever asked a question and had it
answered by the Oracle equivalent of Tom Lane?
