This is what you want to do.  VACUUM FULL is the slow way--much, much 
slower--and it is not needed to clean up from wraparound issues.  Here's

And here's some notes about why you should avoid VACUUM FULL:

(Note that you don't have a good CLUSTER implementation in your 8.1 
server, so using that to clean up tables isn't an option)
