Description
Currently the contrib.postgres ArrayField implements no special handling for choices, which makes it pretty useless with choices; you can specify your choices as a list of possible arrays for the ArrayField to contain. This is, I suppose, consistent in some technical sense, but rarely if ever useful in practice. It's very handy to use an ArrayField with choices to implement a multiple-choice field. We already have a TypedMultipleChoiceField form field in Django, so the implementation for this is just a trivial enhancement to the ArrayField.formfield method: if self.choices is set, use TypedMultipleChoiceField as the form class, with the base_field used to determine the expected type.
Any objections to this before I submit a PR for it?

Here is a preliminary patch. Obviously needs some more work, but it's a start...

I've updated the patch and clarified the fact that choices should be defined on the base_field, not on the ArrayField itself. Hopefully it's a sensible recommendation!

It would be nice to get this done, it seems such an obvious little change.
