Unless you don't vacuum enough on a bigger database, run out of FSM
pages, and the whole vacuum strategy goes to hell afterwards.  I would
say that running into that issue is *probable* for an 8.3 install of any
significant size, whereas the odds of running into a regression in 8.4
relative to 8.3 is pretty low.  The whole "the older version is always
more reliable" mantra doesn't make sense when you've got a major known
issue in the older release that just goes away by using the newer one,
and I feel that's the case with 8.4 vs. 8.3.
