Description

UniqueConstraint should throw an error when deferrable is combined with parameters which require the usage of an explicit unique index through CREATE UNIQUE INDEX. This was missed when UniqueConstraint.include and UniqueConstraint.opclasses was added. We should also add documentation about this incompatibility.

Thanks, IMO raising an exception is enough, we don't need to document this.

It's a bug in new features added in 7edc6e53a746af995e3b89d53d37938dd8fc46aa and 8c7992f658e1125f8dc20b19206e8bbbe4187372.
