-- ============================================================
-- 桃育种系统 - 亲本资源表 (bre_germplasm)
-- ------------------------------------------------------------
-- 依据: doc/桃育种系统业务功能规划报告.md (2026-07-28) 模块1
-- 对齐: DPB 框架审计字段约定 (app/core/base_model.py)
--       id / uuid / is_deleted / created_time / updated_time /
--       deleted_time / created_id / updated_id / deleted_id
-- 用途: 建表后由「代码生成器」导入，一键生成前后端 CRUD
-- 运行: psql -h localhost -U dpb -d dpb -f backend/sql/bre_germplasm.sql
-- 说明: 可直接重复执行 (CREATE TABLE / INDEX / COMMENT 均带 IF NOT EXISTS)
