Right; that just got implemented a couple of months ago. See the news from http://www.postgresql.org/community/weeklynews/pwn20100214 for a summary of how the code was gyrated around to support that. This is a tough situation to get out of in <9.0 because VACUUM FULL is slow and takes an exclusive lock on the table. That tends to lead toward an unpredictable window for required downtime, which is never good.
