So you'd be able to write policies that allowed you to do an
INSERT/UPDATE ... RETURNING, where the WITH CHECK part of the SELECT
policy allowed you see the new row, but then if you tried to SELECT it
later, the USING part of the policy might say no.
That seems pretty confusing. I would expect a row to either be visible
or not, consistently across all commands.
