Status of enable_profile_selector with oauth 2

Question

With the new OAuth2 JavaScript SDK calls, I see no documentation for enable_profile_selector. How do we get permissions to post to a fan page from the JavaScript SDK?

Or, is the idea that once they've given us manage_pages permission on their account, we can request access tokens and do everything without additional permission on any page?

It does appear that after being granted manage_page permissions, running this fql query returns no results:

select publish_stream from permissions where uid = FAN_PAGE_ID

This used to be how we'd verify that we have permission to post to the page.

Thanks, Tom
