This makes it much more convenient to use in the common case that you want to flush all the WAL. (Passing pg_current_wal_insert_lsn() as the argument doesn't work for the same reasons as explained in the comments: we need to be back off to the beginning of a page if the previous record ended at page boundary.) I plan to use this to fix the issue that Arseny Sher called out at https://github.com/neondatabase/neon/pull/7288#discussion_r1660063852
