Recently, there was a question on
[https://stackoverflow.com/a/79662455/67579 StackOverflow] about how to
query a JSON field that has an array, to look if the array contains at
least one of the items.
A bit surprising, but the `?|` operator does that, indeed
[https://www.postgresql.org/docs/9.5/functions-json.html according to the
docs], this use-case is not (well) documented in Django, and `keys`
evidently suggests that it is for dictionaries.
I'm wondering if we should include such cases in the documentation, so add
an example where the JSON blob is an array of strings for example, and
demonstrate how it is filtered.
