**Smart Database Configuration:**
- Auto-detects environment: Railway vs Local development
- Tests PostgreSQL connection before using it
- Falls back to SQLite if PostgreSQL unavailable
- Preserves Railway DATABASE_URL when present
**Environment Detection Logic:**
1. Railway: Uses Railway's DATABASE_URL (PostgreSQL)
2. Local with DATABASE_URL: Uses specified database
3. Local with PostgreSQL running: Uses PostgreSQL
4. Local without PostgreSQL: Falls back to SQLite
**New Management Command:**
- `check_db`: Diagnose database configuration and connection
- Shows current engine, connection status, table count
- Provides troubleshooting tips for PostgreSQL setup
**Solves the Compatibility Problem:**
- Local development: Works without PostgreSQL setup (SQLite fallback)
- Railway production: Always uses PostgreSQL (via DATABASE_URL)
- No more "works locally but fails on Railway" issues
- No more "needs PostgreSQL locally to test Railway compatibility"
**Benefits:**
- Seamless development experience
- Production-development parity when PostgreSQL available
- Graceful degradation to SQLite when needed
- Zero configuration required for basic development
