チャットにはどのくらいの追加ディスク容量が必要ですか？

That’s not something I have direct experience doing, but here is an older answer form another topic:

You can run the following commands to see which tables are taking up the most disk space

./launcher enter app
su - postgres
psql discourse

SELECT nspname || '.' || relname AS "relation",
    pg_size_pretty(pg_total_relation_size(C.oid)) AS "total_size"
  FROM pg_class C
  LEFT JOIN pg_namespace N ON (N.oid = C.relnamespace)
  WHERE nspname NOT IN ('pg_catalog', 'information_schema')
    AND C.relkind <> 'i'
    AND nspname !~ '^pg_toast'
  ORDER BY pg_total_relation_size(C.oid) DESC
  LIMIT 20;
