Phase I vacuum gives the page a once-over after pruning and freezing to check that the values of all_visible and all_frozen agree with the result of heap_page_is_all_visible(). This is meant to keep the logic in phase I for determining visibility in sync with the logic in phase III. Rewrite the assertion to avoid an Assert(false). Suggested by Andres Freund.
