This commit changes pg_basebackup so that it specifies PROGRESS option in BASE_BACKUP replication command whether --progress is specified or not. This causes the server to estimate the total backup size and report it in pg_stat_progress_basebackup.backup_total, by default. This is reasonable default because the time required for the estimation would not be so large in most cases. Also this commit adds new option --no-estimate-size to pg_basebackup. This option prevents the server from the estimation, and so is useful to avoid such estimation time if it's too long.
