Avoid BufferGetPage() calls in heap_update() BufferGetPage() isn't cheap and heap_update() calls it multiple times when it could just save the page from a single call. Do that. While we are at it, make separate variables for old and new page in heap_xlog_update(). It's confusing to reuse "page" for both pages.
