# PostgreSQL Setup Complete ✅

## Database Configuration
- **PostgreSQL Version**: 17.5
- **Installation Path**: `/Library/PostgreSQL/17/bin/`
- **Database Name**: `risk_module_db`
- **User**: `postgres`
- **Password**: None (trust authentication enabled)
- **Host**: `localhost`
- **Port**: `5432`

## Connection String
```
postgresql://postgres@localhost:5432/risk_module_db
```

## Python Dependencies Installed
- `psycopg2-binary==2.9.10`
- `python-dotenv==1.1.0`

## Python Path
```
/Library/Frameworks/Python.framework/Versions/3.13/bin/python3
```

## Verification Tests Passed
- ✅ PostgreSQL server running
- ✅ Database `risk_module_db` created
- ✅ Connection without password works
- ✅ Python PostgreSQL connection successful
- ✅ All required dependencies installed

## Environment Variables for Implementation
```bash
USE_DATABASE=false              # Start with file mode
DATABASE_URL=postgresql://postgres@localhost:5432/risk_module_db
DB_POOL_SIZE=5
ENVIRONMENT=development
```

## Notes for Implementing Claude
1. **Authentication**: Local connections use "trust" authentication (no password required)
2. **Backup**: Original config backed up at `/Library/PostgreSQL/17/data/pg_hba.conf.backup`
3. **Service Management**: Restart with `sudo -u postgres /Library/PostgreSQL/17/bin/pg_ctl -D /Library/PostgreSQL/17/data restart`
4. **Database Ready**: Schema can be created immediately - database is empty and ready for tables

## Ready for Implementation
The database is fully set up and ready for the migration plan implementation. The implementing Claude can proceed directly to Phase 1 of the database migration plan.
