Implementations

impl SystemRelation

pub fn column_names(self) -> Vec<String>

impl SystemRelation

pub fn all() -> impl Iterator<Item = Self>

pub const fn namespace(self) -> &'static str

pub const fn name(self) -> &'static str

pub fn oid(self) -> i64

pub const fn kind(self) -> &'static str

pub fn at(schema: &str, name: &str) -> Option<Self>

impl SystemRelation

pub const fn tracks_serializable_reads(self) -> bool

PostgreSQL’s pinned system catalogs and their metadata views are outside SSI. AGE catalogs are ordinary extension tables and retain data predicates.

pub fn qualified_name(self) -> String

pub fn from_qualified_name(name: &str) -> Option<Self>

pub fn object_id(self) -> [u8; 16]

Immutable built-ins retain the same identity in every session; lock managers retain database affinity.

pub fn bootstrap_security(self) -> BoundTableSecurity

pub const fn view_sources(self) -> &'static [Self]

PostgreSQL 18 view range-table order, followed by expression and range-table subqueries. Repeated references preserve that order; consumers own recursion and lock retention.
