Module constraint_metadata 

Normalize durable constraint names and identities through a caller-owned identity allocator.

Modules

identity

Allocate constraint incarnations and preserve legacy NOT NULL OIDs during initial migration.

Structs

ConstraintNameScope

Explicit names share their relation’s event namespace; automatic names also avoid every constraint in the containing schema.

Enums

CatalogOidClass

ConstraintMetadataError

Traits

CatalogObjectAllocator

Declaration normalization requests identities from its caller. Execution reserves public addresses; isolated declarations and initial migration can derive candidates before validating the complete catalog.

Functions

foreign_key_provenance_matches

Attachment provenance tracks one local row even after its name or enforcement flags change. Legacy entries may still lack the independent catalog identity.

foreign_keys_match_without_object_id

materialize_column_key_constraints

materialize_constraint_metadata

materialize_constraint_metadata_with_names

Validate explicit local names before excluding schema-wide names from automatic selection.
