Description (last modified by Tim Graham)

According #29641 and #29547, add support of conditional unique constraint.

Postgresql and sqlite support it as unique index: CREATE UNIQUE INDEX ... WHERE condition, for unsupported databases this constraint will not be applied at all.

I don't think deprecating index_together is currently planned but ​the documentation do suggest it might be in the future.

I adjusted the ticket description and created #30063 so this ticket can focus on UniqueConstraint(condition).
