||
|
|
- **Testing**: SQLite for fast, reliable integration tests
|
||
|
|
|
||
|
|
### **✅ Key Features**
|
||
|
|
- Connection pooling (PostgreSQL)
|
||
|
|
- Automatic table creation
|
||
|
|
- Comprehensive error handling

## **Migration Path**
|
||
|
|
|
||
|
|
### **Current State**
|
||
|
|
- ✅ **Flexible client implemented and tested**
|
||
|
|
- ❌ **Legacy components still use PostgreSQL client**
|
||
|
|
- ❌ **Some integration tests need updating**
|
||
|
|
|
||
|
|
### **Next Steps**
|
||
|
|
1. **Update existing components** to use flexible client
|
||
|
|
2. **Replace PostgreSQL-specific integration tests**
|
||
|
|
3. **Update safety framework tests** to use flexible client
|
||
|
|
4. **Remove old PostgreSQL-only client**
