It's also possible to overestimate the benefit of vacuum full, leading 
to people vacuum full'ing almost constantly, then complaining about 
performance due to the associated overhead. I think there have been more 
people on this list whose performance problems were caused by 
unnecessary full vacs than by those whose performance problems were 
caused by insufficient full vacs.
