Hi,
Here is the result of the command actually tables "audit_log" are very large.
What can I do to prevent the file system fills up?

psql engine -c "SELECT nspname || '.' || relname AS relation,
     pg_size_pretty(pg_relation_size(C.oid)) AS size
   FROM pg_class C
   LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace)
   WHERE nspname NOT IN ('pg_catalog', 'information_schema')
   ORDER BY pg_relation_size(C.oid) DESC
   LIMIT 20;"
