I have modified the comment in hash_xlog_init_meta_page and a
corresponding function for bitmap page. However, I think adding
anything about not using log_newpage in _hash_init doesn't sound good
to me. I think you have suggested it so that we don't forget the
reason for not using log_newpage, but I think that is overkill. Let
me know if you have any other concerns?
