1. Should we add some tests?
2. When the error occurs, eval_infallible will call UDF for each row, right? Not sure if it has any problems in this case. I think it’s not a very big deal. 🤔️

1. Should we add some tests?

Yes. But I couldn't think of a way to test this in sqllogictest. 🤔️

2. When the error occurs, eval_infallible will call UDF for each row, right? Not sure if it has any problems in this case. I think it’s not a very big deal. 🤔️

Yes. I'm also not sure about it. I'll be soon working on fixing #11586. At that time I may put the responsibility of eval_infallible on each function. And for UDF it may simply fill all values to null.
