-- 数据分析模块数据库 Schema（Supabase/Postgres）
|

-- ============================================
|
||
-- 用途：创建 analytics_* 表、索引、RLS策略、RPC函数
|
||
-- 参考：`docs/ANALYTICS_DB_DESIGN.md`
|
||
--
|
||
-- 执行顺序：
|
||
-- 1. 先执行基础业务表（`01_create_tables.sql`）
|
||
-- 2. 再执行本文档（`ANALYTICS_DB_SCHEMA.sql`）
|
||
-- 3. 最后执行 `ANALYTICS_TEST_SEED.sql` 插入测试数据（受 RLS 影响，需较高权限执行）
