Well, that implies some file-format-level incompatibility between 8.0.0
and 8.0.1-r3, which would be quite disturbing ... especially if we had
more than one report of it. As is, I suspect it means you had a broken
build of 8.0.1-r3 for some reason. One possibility is a different set
of configuration parameters from what was used to build 8.0.0 (though
offhand I can't think of anything that would yield this particular
failure).
You might try comparing the results of
select ev_action from pg_rewrite where ev_class = 'pg_user'::regclass;
from the two builds.
