Expand description

Durable table-level constraints that do not fit in ColumnDef.

serde(default) on the catalog field containing this structure keeps databases written before constraint persistence backward compatible.

Fields§

§dropped_attributes: Vec<DroppedAttribute>

Physical attribute metadata retained after a column is removed from the live schema.

§columns_declared: Option<bool>

Distinguish a declared zero-column SQL relation from a schema-free document table. Missing legacy metadata retains inference from existing columns.

§checks: Vec<TableCheck>§foreign_keys: Vec<ForeignKey>§key_constraints: Vec<TableKeyConstraint>§persistence: RelationPersistence

Stored alongside the table definition so reopen preserves pg_class.relpersistence for unlogged tables.

§on_commit: OnCommitAction

Permanent and unlogged tables always use the default. Temporary tables are session-local and therefore never write this field to disk.

§hierarchy: TableHierarchy

Durable relation hierarchy and partition-bound metadata.

§catalog_oids: Option<RelationCatalogOids>

The relation’s public OIDs, allocated when it was created. Tables created before OIDs were recorded derive them from their identity.

§row_type_array_name: Option<String>

The generated row-array type name, which can move independently when an explicit type takes its name.
