Well let's take it a step back because I think you are on to something here.
Our customers will "directly" see a benefit from the changes Greg made
for 8.3 on the space reductions. Not only is a benefit for on disk
storage but it is also a direct performance benefit. When my customers
say... why does 8.3 take so much less space than 8.2, I will tell them
and further expound on it being one of the key components to their
greater performance.
Most of out customers however will not notice one of our key
contributions which was the multi-worker autovacuum. Yes it is
important. Yes we have specific customers that will benefit greatly from
it but the mass majority will not.

I agree with this as well. However, I am starting to wonder if the
"release notes" is the place for this. I am starting to think that
instead we need a white paper on the release (or each release) that is
categorized and reasonably in depth on "why" 8.3 (or 8.4 etc..).
