[I] ScalarFunctionExpr does not preserve the nullable flag on roundtrip [datafusion]
ccciudatu opened a new issue, #13829:
URL: https://github.com/apache/datafusion/issues/13829
### Describe the bug
A physical plan that contains scalar functions will always set the nullable flag to `true` after deserialization.
### To Reproduce
The `coalesce` function results in a non-nullable field. However, if the plan is serialized and deserialized, the same field will be nullable.
A test to showcase exactly this will be included in the upcoming PR.
### Expected behavior
The plan schema should stay the same after a roundtrip.
### Additional context
