+-- Event ID 타입 변경 DDL (UUID → VARCHAR(50)) - PostgreSQL
+-- ====================================================================================================
+-- 작성일: 2025-10-29
+-- 작성자: Backend Development Team
+-- 설명: Event 엔티티의 eventId가 String 타입으로 변경됨에 따라 관련 테이블들의 event_id 컬럼 타입을 UUID에서 VARCHAR(50)으로 변경합니다.
+-- 영향 범위:
+--   - events 테이블 (Primary Key)
+--   - event_channels 테이블 (Foreign Key)
+--   - generated_images 테이블 (Foreign Key)
+--   - ai_recommendations 테이블 (Foreign Key)
+--   - jobs 테이블 (Foreign Key)
