I'm still working on getting through our test cases and benchmarks,
but one thing I can say for sure -- a freshly loaded database under
8.3beta4 is over 13% smaller than the exact same database freshly
loaded into 8.2.5. It went from 216GB to 187GB.
Of course, the down side of this is that it'll be that much longer
before we can brag about having a TB database....
