Required Methods

fn registered_runtime_function_may_mutate_engine(&self, name: &str) -> bool

fn domain_by_oid(&self, oid: u32) -> Option<StoredDomain>

fn sequence_persistence( &self, name: &str, ) -> Result<Option<RelationPersistence>, String>

fn table_persistence( &self, name: &str, ) -> Result<Option<RelationPersistence>, String>
