Comment (by charettes):

 @BlindHunter, concurrent index creation has many
 [http://www.postgresql.org/docs/current/static/sql-createindex.html#SQL-
 CREATEINDEX-CONCURRENTLY documented caveats] hence why it's not enabled by
 default.

 I don't think we should expect newcomers to Django/PostgreSQL to make sure
 all their index have been correctly created even if their migration ran
 fine. That's the reason we're planing to make it an ''opt-in'' feature and
 not the default behavior, just like it's not the default in PostgreSQL
 itself.

 In the meanwhile I suggest you create your own subclass of
 `Alter(Index|Unique)` operations and override `database_forward` to issue
 the desired SQL.
