Postgres supports [http://www.postgresql.org/docs/current/static
/functions-conditional.html#FUNCTIONS-GREATEST-LEAST GREATEST and LEAST]
query expressions. These could easily be implemented in django by
subclassing the
[https://github.com/django/django/blob/master/django/db/models/functions.py#L8-L29
Coalesce] query expression and changing the `function` attribute to
`'GREATEST'` or `'LEAST'` respectively.
I'm not sure which other databases support this, so perhaps this can only
be added to `contrib.postgres`.
If this isn't appropriate for core, I'm happy to create a small PyPI
package instead.
