+-- 简化镜像管理：移除 Image 表，直接在 HostImage 中存储镜像信息
+
+-- 1. 备份现有数据（如果需要恢复）
+-- 创建临时表保存现有的 host_images 数据
+CREATE TEMP TABLE temp_host_images AS
+SELECT 
+    hi.id,
+    hi.host_id,
+    i.remote_alias as image_id,
+    i.name,
+    i.os_type,
+    i.remote_alias,
+    COALESCE(i.icon, SPLIT_PART(i.remote_alias, '/', 1)) as icon,
+    hi.fingerprint,
+    hi.alias,
+    hi.size,
+    hi.status,
+    hi.error_message,
+    hi.synced_at,
+    hi.created_at,
+    hi.updated_at
+FROM host_images hi
+JOIN images i ON hi.image_id = i.id;
+
+-- 2. 删除外键约束和旧表
+DROP TABLE IF EXISTS host_images;
+DROP TABLE IF EXISTS images;
+
+-- 3. 创建新的 host_images 表
+CREATE TABLE host_images (
+    id SERIAL PRIMARY KEY,
+    host_id INTEGER NOT NULL,
+    image_id VARCHAR(100) NOT NULL,
+    name VARCHAR(100) NOT NULL,
+    os_type VARCHAR(50) NOT NULL DEFAULT 'Linux',
+    remote_alias VARCHAR(200) NOT NULL,
+    icon VARCHAR(50),
+    fingerprint VARCHAR(100),
+    alias VARCHAR(100),
+    size INTEGER NOT NULL DEFAULT 0,
+    status VARCHAR(20) NOT NULL DEFAULT 'pending',
+    error_message TEXT,
+    synced_at TIMESTAMP,
+    created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
+    CONSTRAINT fk_host_images_host FOREIGN KEY (host_id) REFERENCES hosts(id) ON DELETE CASCADE,
+    CONSTRAINT uq_host_images_host_image UNIQUE (host_id, image_id)
+);
+
+-- 4. 创建索引
+CREATE INDEX idx_host_images_host_id ON host_images(host_id);
+
+-- 5. 恢复数据（将 remote_alias 转换为 image_id 格式）
+INSERT INTO host_images (
+    host_id, image_id, name, os_type, remote_alias, icon,
+    fingerprint, alias, size, status, error_message, synced_at, created_at, updated_at
+)
+SELECT 
+    host_id,
+    LOWER(REPLACE(REPLACE(remote_alias, '/', '-'), '.', '-')) as image_id,
+    name,
+    os_type,
+    remote_alias,
+    icon,
+    fingerprint,

+    status::VARCHAR,
+    error_message,
+    synced_at,
+    created_at,
+    updated_at
+FROM temp_host_images;
+
+-- 6. 清理临时表
+DROP TABLE temp_host_images;
