Hello Carlos,

Thank you for taking the time to reproduce the issue against the upcoming
1.11 release.

It looks like `Index` class doesn't use the same name generation logic as
the schema editor for some reason[0] so it will be have to be adjusted in
a similar way.

Could you file a new ticket[1] referencing this thread and detailing the 
issue
you are encoutering? It should be eligible for a backport since this is a 
bug
in a newly introduced feature.

Until a 1.11.x version fixing the issue is released you can work around the
issue by defining an Index(name)[2] manually.

Cheers,
Simon
