### Describe the bug Type coercion of `COALESCE` returns Int even when there are string arguments. This is not always correct, as '' is a valid string but cannot be converted to int. ### To Reproduce ```sql SELECT coalesce(1,'') ``` should be typed as a string, not int ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
