Description

Hi, I have problem migrating some 3rd party database with Django migrations. I have used router for controlling which apps are allowed to be migrated on this database. But I have problem with HStoreExtension operation because these operations don't check if they are allowed. And because I have limited rights and I am controlling only my schema on that database I will get error while installing hstore.

Source of trouble:
​https://github.com/django/django/blob/master/django/contrib/postgres/operations.py#L18

Work-around/proposal for CreateExtension class:

class RoutingHStoreExtension(HStoreExtension):
    def database_forwards(self, app_label, schema_editor, from_state, to_state):
        if not router.allow_migrate(schema_editor.connection.alias, app_label):
            return
        return super().database_forwards(app_label, schema_editor, from_state, to_state)

Version: 2.1 → master

Agreed, we should check router.allow_migrate(schema_editor.connection.alias, app_label, **self.hints) in both CreateExtension.database_forwards() and database_backwards().
