This view also doesn't show vacuum progress across a partitioned table.
For comparison:
pg_stat_progress_create_index (added in v12) has:
partitions_total
partitions_done
pg_stat_progress_analyze (added in v13) has:
child_tables_total
child_tables_done
pg_stat_progress_cluster should have something similar.
