> Allow skipping of WAL for new tables and indexes if wal_level is 'minimal' (Noah Misch)
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.
