This is a known bug in 7.2 --- IIRC, vacuum can get confused by some
situations involving rollback after SELECT FOR UPDATE. It's pretty
harmless other than preventing you from using VACUUM FULL.
You can update to 7.3 to get the fix, or I think that just doing a
dummy SELECT * FOR UPDATE will clear the condition.
7.2.3 fixes some but not all cases of this, so an update to 7.2.3
might or might not help.
