izveigor opened a new issue, #6779:
URL: https://github.com/apache/arrow-datafusion/issues/6779
### Describe the bug
`ArrayFill` function can return lists with different dimensions:
```
postgres=# select array_fill(a, b) from fills;
array_fill
-----------------------------------
{{2,2}}
{5,5,5,5,5,5,5}
{{{{1}}}}
{{4,4,4},{4,4,4},{4,4,4},{4,4,4}}
(4 rows)
```
The standard `return_type` function cannot determine the type for 'dynamic'
functions. because it prefers to assign one type to the whole column and does
not take into account their arguments.
