This is not particularly surprising in 8.1 --- it has some race
conditions that can result in that type of error if vacuum (or anything
else) tries to open a table just as something else is deleting it.
We fixed that around 8.2, but it's really just a cosmetic issue
(you'd rather the message was "relation foo does not exist" ...)
I don't see any reason to worry.
