Kyotaro Horiguchi authored that one.  (I committed it.)  The commit message
noted characteristics, some of which may deserve mention in the notes:

- Crash recovery was losing tuples written via COPY TO.  This fixes the bug.
- Out-of-tree table access methods will require changes.
- Users setting a timeout on COMMIT may need to adjust that timeout, and
  log_min_duration_statement analysis will reflect time consumption moving to
  COMMIT from commands like COPY.
- COPY has worked this way for awhile; this extends it to all modifications.
