Enum AutoIncrementKind 

pub enum AutoIncrementKind {
    Serial,
    IdentityAlways,
    IdentityByDefault,
    Legacy,
}

PostgreSQL syntax that supplies an omitted column value from an implicit sequence. SERIAL is a sequence-backed default, while identity columns retain a separate generation attribute and do not have a column default.

Variants

Serial

IdentityAlways

IdentityByDefault

Legacy

Catalogs written before sequence provenance was persisted cannot distinguish SERIAL from identity syntax. Preserve their historical table-counter behavior instead of guessing and changing stored data.
