Autovacuum looks at the modification statistics (they count how much
modifications happened on the table), and decides whether it's time to
VACUUM (reclaim empty space) and ANALYZE (update column value
distributions) the table.
The exact thresholds for Autovacuum to kick in are configurable, see the
docs.
