1) public.users
‒ 회원(=auth.users)의 확장 테이블로 사용
‒ 집계형 필드만 둡니다.

id  (PK, auth.users FK)  
membership_level TEXT  → FK public.membership_levels.level  
my_zzim           INT  -- 내가 받은 찜 총합  
zzim_mile         INT  -- 누적 마일리지  
available_zzim_mile INT -- 사용가능(미소모) 마일리지  
today_zzim_count  INT  
today_zzim_date   DATE
created_at, updated_at


2) public.membership_levels

level               PK ('basic','premium'…)  
api_call_limit       INT
daily_zzim_limit     INT
max_zzim_mileage     INT
mileage_per_zzim     INT


3) public.user_markets

id          PK  
user_id     FK → public.users.id  
my_markets  JSONB       -- [{ market_url , … , zzim_received_count , … }]  
created_at, updated_at

4) 뷰(View) 하나 추가하면 코드가 훨씬 단순합니다.

CREATE OR REPLACE VIEW public.v_user_market_stats AS
SELECT 
   u.id            AS user_id,
   u.membership_level,
   u.available_zzim_mile,
   u.my_zzim,
   u.zzim_mile,
   m.my_markets
FROM public.users u
LEFT JOIN public.user_markets m ON m.user_id = u.id;


-- 한번만 실행
WITH s AS (
  SELECT user_id,
         COALESCE(SUM((m->>'zzim_received_count')::INT),0) AS total_zzim
  FROM public.user_markets,
       LATERAL jsonb_array_elements(my_markets) m
  GROUP BY user_id
)
UPDATE public.users u
SET my_zzim = s.total_zzim
FROM s
WHERE u.id = s.user_id;
