Functions ¶
func BindDataTransforms ¶
func BindDataTransforms(artifact migration.Artifact, transforms []migration.DataTransformDescriptor) (migration.Artifact, error)
BindDataTransforms inserts checksum-only callback identities immediately before the final PostgreSQL schema assertion without changing the artifact format or physical planner contract.
func DataOnlyArtifact ¶
func DataOnlyArtifact(name string, planner migration.Planner, before, after schema.Manifest) (migration.Artifact, error)
DataOnlyArtifact creates the ordinary assertion-only PostgreSQL phase that receives a compiled transform when the manifest itself is unchanged.
func ValidateVersionedTransition ¶
func ValidateVersionedTransition(before, after schema.Snapshot, transforms []migration.DataTransformDescriptor) error
ValidateVersionedTransition refuses transform-backed field changes that would leave retained snapshots on the previous structure.
