聊天需要多少额外的磁盘空间？

我没有直接的经验，但这是我从另一个主题中找到的一个旧答案：

您可以运行以下命令来查看哪些表占用的磁盘空间最多

./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;
