One minor side effect of this change is the original idea of comparing
pg_stat_progress.num_dead_tuples to pg_stat_all_tables.n_dead_tup
column becomes less obvious. I presume the release notes for
pg_stat_progress_vacuum will be updated to also include this column
name change as well, so maybe that's enough for folks to figure things
out? At least I couldn't find anywhere in the docs where we have
described the relationship between these columns before. Thoughts?
