There is a known form of this problem that does not go away on restart.
I can't recall at the moment if it's fixed in 7.2.3 or not (been a long
day ...) It is definitely fixed for 7.3 though.
If you don't want to update to 7.3 in the near future, I think there is
a workaround involving doing SELECT FOR UPDATE to clear out the bogus
state. Check the pghackers archives from back around August for
details.
