dbx-main/scripts/sql/dispatch_db_init.sql

-- =====================================================================
-- dispatch_db 초기화 스크립트 (PostgreSQL) — 말레이시아 TikTok 출고관리
-- =====================================================================
-- 멱등(idempotent): 여러 번 실행해도 안전. 기존 데이터를 삭제하지 않는다.
--
-- ⚠️ 실행 전 사용자 승인 + 백업 확인 필수. DROP/TRUNCATE 없음.
--
-- 실행 방법 (운영 PostgreSQL 컨테이너명: postgres-db):
--
--   1) DB / 역할 / 스키마 생성 (superuser 로 1회)
--      read -s -p "dispatch_app password: " APP_PWD; echo
--      docker exec -i postgres-db psql -U postgres \
--          -v app_password="$APP_PWD" \
--          < scripts/sql/dispatch_db_init.sql
--
--   2) main-app .env 에 연결 정보 등록
--      DISPATCH_DB_URL=postgresql://dispatch_app:<APP_PWD>@postgres-db:5432/dispatch_db
--
--   3) main-app 재기동
--      cd /opt/www/main && docker compose up -d --build web
--
-- 주의:
--   - 기존 DB 가 있으면 DROP 하지 않는다(CREATE DATABASE 는 미존재 시에만).
--   - 비밀번호는 절대 Git 에 커밋하지 않는다. psql -v 로만 전달.
--   - 개인정보(고객 이름/주소/전화)는 저장하지 않는 구조다(컬럼 자체가 없음).
--   - 작업 기준 키: order_id / package_id / tracking_id / seller_sku / quantity.
