Hi,
> Exactly Tom, I see no fundamental problem for it not to be implemented, since comparison operator is already
implemented.In fact, MIN/MAX should work for all types for which comparison operator is defined.
On second thought, this should work reasonably well.
PFA a WIP patch. At this point it implements only MAX(record), no MIN, no tests:
```
=# SELECT MAX(row(year, month)) FROM (VALUES(2025, 1), (2024,2)) x(year, month);
max
----------
(2025,1)
```
One thing I'm not 100% sure of is whether record_larger() should make
a copy of its arguments or the current implementation is safe.
