```
@db.register_function(replace=True)
def my_function(a):
    return a.upper()
```
If `replace=True` then this function will be registered even if a `my_function` of arity 1 has already been registered previously.

It defaults to `False` though which means the Database object tracks what functions and arities have been registered in the past and silently ignores any new attempts to register the same name/arity.
