It depends more on user activity and number/size of indexes than over all
database size from what I've seen.. In one database I have 20ish tables,
some have 70,000ish records but the whole database isn't very big -- VACUUM
takes a while because of the amount of UPDATE'd and DELETE'd records I have
every day, and the number of indexes (lots!)....
