-### Database Scripts
-SQL scripts are located in `sql/` directory with support for multiple databases:
-- `sql/postgresql/` - PostgreSQL scripts
-- `sql/mysql/` - MySQL scripts
-- `sql/oracle/`, `sql/sqlserver/`, `sql/dm/`, `sql/kingbase/`, `sql/opengauss/` - Other DB support

-### Database Conversion
-Use `sql/tools/convertor.py` to convert MySQL scripts to other databases:
-```bash
-cd sql/tools
-python3 convertor.py postgres > output.sql
-```

 ### Quick Database Setup with Docker
 ```bash
-cd sql/tools
-docker compose up -d postgres
