Won’t the date generator functions allow you to do this? It has been a long time since I looked at these but I seem to recall functions that would allow the implementation of the function you want. Take a look at the documentation.

Then you would pass to it month + year to get a date? If not, how would I implement such a type? Extend nth_day_of_the_week_in_month?
