Tom, any opinions to offer here? pg_stat_all_tables is currently at 22
columns (this takes two full lines on my terminal with a font size at
13). With the first patch of what's proposed on this thread there
would be 24 columns. Perhaps it would be time to split the vacuum
statistics into a new view like pg_stat_tables_vacuum or similar?
