 Description   

The problem reported in MDEV-27098 for TIME is repeatable with the INET6 data type.

DROP TABLE IF EXISTS t1;
 
CREATE TABLE t1 (d INET6);
 
INSERT INTO t1 VALUES ('1::0'), ('12::0');
 
SELECT * FROM t1 WHERE d >= ALL (SELECT * FROM t1);


+------+
 
| d    |
 
+------+
 
| 1::  |
 
| 12:: |
 
+------+

The expected result should contain only one with with the maximum value '12::'.
