-- PostgreSQL 数据库 Schema
-- 用于创建 media 和 users 表

-- 创建 media 表
CREATE TABLE IF NOT EXISTS media (
  id SERIAL PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  type VARCHAR(50) NOT NULL,
  rating INTEGER,
  notes TEXT,
  platform VARCHAR(100),
  date DATE,
  created_at TIMESTAMP DEFAULT NOW(),
  updated_at TIMESTAMP DEFAULT NOW()
);

-- 创建 users 表
CREATE TABLE IF NOT EXISTS users (
  id SERIAL PRIMARY KEY,
  username VARCHAR(100) UNIQUE NOT NULL,
  password VARCHAR(255) NOT NULL,
  created_at TIMESTAMP DEFAULT NOW()
);

-- 创建索引以优化查询性能
CREATE INDEX IF NOT EXISTS idx_media_type ON media(type);
CREATE INDEX IF NOT EXISTS idx_media_rating ON media(rating);
CREATE INDEX IF NOT EXISTS idx_media_date ON media(date);
CREATE INDEX IF NOT EXISTS idx_users_username ON users(username);
