Support for `CREATE INDEX CONCURRENTLY` on PostgreSQL would be a plus. I
think it was previously discussed to add it as the default behavior, but
that probably has undesired side-effects for some cases. I imagine
`concurrently=False` as an option to the index-class.

By default, all indexes are created inside a transaction which does not
work together with `concurrently`.

Comment (by Simon Charette):

Related to #21039. This should be doable through class based indexes but
I'm not sure what is the best solution here, add `concurrent` to the base
index class and error out on unsupported backends or provide it through
`django.contrib.postgres`.
