No such plans at the moment. What do you you need them for?
I have used unique partial indexes to enforce business rules like "Active users must have a unique phone number, but there may be any number of inactive users with the same phone number" ``` create unique index ix_active_phones on users (phone) where active = true ; ``` -- Jared Beck • (607) 216-5373 • jared@jaredbeck.com
