This is a known problem which is fixed in 7.3. I believe in 7.2 you can
make the error go away by doing "SELECT * FROM table FOR UPDATE" --- but
it might come back again. (VACUUM gets confused by some scenarios
involving aborted SELECT FOR UPDATE commands; see the pghackers archives
from last August or so for details.)
IIRC, Red Hat has back-patched the 7.3 fix into their latest 7.2.3-based
release, but it was never back-patched in community sources.
