## Schema 变更规则
|
||
|
||
修改任何影响 PostgreSQL schema 的内容（迁移脚本/DDL/表定义）时，必须同步更新 `docs/database/`：
|
||
|
||
1. **变更说明**：新增/修改/删除的表、字段、约束、索引
|
||
2. **兼容性**：对 ETL、后端 API、小程序字段映射的影响
|
||
3. **回滚策略**：如何撤销（DDL 回滚 / 数据回填）
|
||
4. **验证步骤**：至少 3 条校验 SQL
|
||
|
||
## RLS 视图双 Schema 规则
|
||
|
||
新建 DWS/DWD 表的 RLS 视图必须同时在原 schema（如 `dws`）和 `app` schema 创建：
|
||
|
||
```sql
|
||
-- 1. 原 schema
|
||
CREATE VIEW dws.v_xxx AS SELECT ... WHERE site_id = current_setting('app.current_site_id')::int;
|
||
|
||
-- 2. app schema（后端通过此路径访问）
|
||
CREATE VIEW app.v_xxx AS SELECT ... WHERE site_id = current_setting('app.current_site_id')::int;
|
||
```
|
||
|
||
回滚需逆序 DROP 两个 schema 的视图。只在原 schema 创建会导致后端查询失败。
|
||

|

|
||
## 测试规范
|
||
|
||
- 数据库操作使用测试库（`TEST_DB_DSN` / `TEST_APP_DB_DSN`），禁止连正式库
|
||
- 迁移脚本在测试库执行后需验证表结构
