Major database migration to modernize the AI trading system:
• **Database Migration**:
- Add PostgreSQL 15 and Redis 7 services to docker-compose
- Create comprehensive PostgreSQL schema with proper indexes and triggers
- Implement DatabaseInterface for multi-database support
- Add automatic environment-based database selection
• **Infrastructure**:
- PostgreSQL: ACID transactions, better concurrency, JSON support
- Redis: High-performance caching layer (prepared for future use)
- Docker services with health checks and dependency management
- Persistent volumes for data safety
• **Code Refactoring**:
- Abstract database operations through DatabaseInterface
- Implement PostgreSQL-specific operations with proper syntax
- Update all SQL queries to support both SQLite and PostgreSQL
- Fix foreign key constraints and data type conversions
• **Migration Tools**:
- Automated data migration script from SQLite to PostgreSQL
- Complete backup and restore procedures
- One-click migration script with validation
• **Compatibility**:
- Backward compatible with existing SQLite deployments
- Environment variable driven database selection
- Preserved all existing functionality and data
🎯 Benefits: Better performance, scalability, and reliability for production deployments

-- PostgreSQL数据迁移脚本
|
|
-- 从SQLite导出的数据转换为PostgreSQL格式
|
|
|
|
-- 注意：这个脚本需要根据实际的SQLite导出数据进行调整
|
|
-- 主要差异：
|
|
-- 1. SQLite的AUTOINCREMENT -> PostgreSQL的SERIAL
|
|
-- 2. 布尔值：SQLite的0/1 -> PostgreSQL的false/true
|
|
-- 3. 日期时间格式可能需要调整
|
|
-- 4. 主键冲突处理：使用ON CONFLICT
|
|
|
|
-- 如果有实际数据，请在这里添加INSERT语句
|
|
-- 例如：
|
|
|
|
-- 插入用户数据（如果有）
|
|
-- INSERT INTO users (id, email, password_hash, otp_secret, otp_verified, created_at, updated_at)
|
|
-- VALUES (...) ON CONFLICT (id) DO NOTHING;
|
|
|
|
-- 插入AI模型配置（如果有自定义）
|
|
-- INSERT INTO ai_models (id, user_id, name, provider, enabled, api_key, custom_api_url, custom_model_name, created_at, updated_at)
|
|
-- VALUES (...) ON CONFLICT (id) DO NOTHING;
|
|
|
|
-- 插入交易所配置（如果有自定义）
|
|
-- INSERT INTO exchanges (id, user_id, name, type, enabled, api_key, secret_key, testnet, hyperliquid_wallet_addr, aster_user, aster_signer, aster_private_key, created_at, updated_at)
|
|
-- VALUES (...) ON CONFLICT (id, user_id) DO NOTHING;
|
|
|
|
-- 插入交易员配置（如果有）
|
|
-- INSERT INTO traders (id, user_id, name, ai_model_id, exchange_id, initial_balance, scan_interval_minutes, is_running, btc_eth_leverage, altcoin_leverage, trading_symbols, use_coin_pool, use_oi_top, custom_prompt, override_base_prompt, system_prompt_template, is_cross_margin, created_at, updated_at)
|
|
-- VALUES (...) ON CONFLICT (id) DO NOTHING;
|
|
|
|
-- 插入系统配置（如果有自定义）
|
|
-- INSERT INTO system_config (key, value, updated_at)
|
|
-- VALUES (...) ON CONFLICT (key) DO UPDATE SET value = EXCLUDED.value;
|
|
|
|
-- 插入内测码（如果有）
|
|
-- INSERT INTO beta_codes (code, used, used_by, used_at, created_at)
|
|
-- VALUES (...) ON CONFLICT (code) DO NOTHING;
|
|

|
-- 数据迁移完成后的验证查询
|
