Previously 0 was reported in pg_stat_progress_basebackup.total_backup if the total backup size was not estimated. Per discussion, our consensus is that NULL is better choise as the value in total_backup in that case. So this commit makes pg_stat_progress_basebackup view report NULL in total_backup column if the estimation is disabled. Bump catversion.
