ThomasAWalker opened a new issue, #13415:
URL: https://github.com/apache/datafusion/issues/13415
### Describe the bug
When group by is used with MAX and a group contains only NaNs the result is
the minimum floating point value.
Similarly MIN returns the maximum floating point value.
### To Reproduce
```
CREATE TABLE input_table (
"row" integer,
"x" double precision
);
INSERT INTO input_table VALUES (1, 'NaN');
SELECT max(input_table.x), min(input_table.x) from input_table GROUP BY
input_table."row";
```
### Expected behavior
In sqlite, postgres and duck both min and max will return NaN
