Use dialect.MySQL, dialect.PostgreSQL, etc instead of these strings. Why do we need this, and not just [3]string{...}?

Uniqueness is too long. Let's change it to Unique.

It does make sense to return true is the error is type ConstraintError as well. Also, please add more details regarding the possible constraint errors.
