Hmm, actually you don't even need the rule, any use of a whole-row Var
for that view will fail:

regression=# select v_baz from v_baz;
ERROR: table row type and query-specified row type do not match
DETAIL: Table row contains 3 attributes, but query expects 2.

The problem is that the ORDER BY on a value that's not part of the
output list generates a hidden "resjunk" column in the view, which
confuses ExecEvalVar. I've applied a patch that will appear in 8.2.5.
