Django get min and max value from PostgreSQL specific ArrayField holding IntegerField(s)

I have an ArrayField in my model holding IntegerFields. I'm looking for the best way in which I can extract the smallest and the biggest integer out of this array.

The Django documentation doesn't give examples of something similar and I wonder if the right way would be finding out how and if I can use aggregation function on this ArrayField or if I can cast this to normal python list of integers somehow and use the build in min, max functions?

Any suggestions for performing this would be helpful. Examples even more.
