key returns a canonical kind-prefixed identifier used for dependency lookups and set membership. Tables, views, and matviews share a namespace (relation namespace in PG), so they use the same prefix "rel:". Functions are identified by schema, name AND signature so that overloaded names (e.g. `publi

// names (e.g. `public.fn(int4)` and `public.fn(text)`) do not collide and
// collapse into a single entry during topo-sort bookkeeping.
func (e *objectEntry) key() string {
	switch e.kind {
	case kindSchema:
		return "schema:" + e.schema
	case kindEnum:
		return "type:" + e.schema + "." + e.name
	case kindTable, kindView, kindMatView:
		return "rel:" + e.schema + "." + e.name

		return "func:" + e.schema + "." + e.name + "|" + funcSignatureKey(e.funcMeta)
	}
	return "unknown:" + e.schema + "." + e.name
}

// sortKey returns the intra-SCC lexicographic key. Matches hard contract C10.
// For functions the signature is appended so overloads have distinct sort
