I want to test with --nomigrations for performance reasons, but I have a
GIN index and it fails because it doesn't execute a `CREATE EXTENSION
btree_gin`.

Comment (by Iuri de Silvio):

I fixed my issue creating the extension on `pre_migrate` signal. I think
it is a reasonable solution to decouple extension setup and index
creation.

I tried some solutions with Django internals but they're not good. Signal
works for me and after some investigation I don't think it should be
handled by Django.

Comment:

I also agree that this shouldn't be handled by Django by default.
