Hi,
In 9.0, some SQL commands can avoid WAL-logging only when
not only archive_mode is off but also max_wal_senders is
zero (new condition since 9.0). But I forgot modifying the
documents about this behavior enough :(
The attached patch adds the description about that new
condition for WAL-logging.
Regards,
