Support for PostgreSQL Arrays

[Danilo Bargen]

It would be nice if Django would natively support PostgreSQL's ​Array Types.

As far as I can tell, django-dbarray provides a correct implementation, using the hooks currently available in the ORM.

The ORM is primarily intended to support field types used in web applications; I don't know what kind of field would best map to a PostgreSQL array.

A Google search for "django postgresql array" turns up the solution, so there's not much to gain in terms of discoverability.

For these reasons, I think this can very well live outside of core. Marking DDN so as to get a second opinion.

I agree that features that only one of the supported database backends support are better supported by external apps when possible.

Fortunately support for Postgres arrays has been added in ​https://github.com/django/django/pull/2485. So the status could be changed from "wontfix" to "fixed", as a reference for people looking for this feature via Google.
