I'm not sure that's a use-case we really need to optimize.  Even with
100,000 empty tables, "vacuumdb --analyze-only --missing-stats-only --jobs
64" completes in ~5.5 seconds on my laptop.  Plus, even if reltuples is 0,
there might actually be rows in the table, in which case analyzing it will
produce rows in pg_statistic.
