There is more to that, no?  It seems to me that anything that opens
PublicationNamespaceRelationId should be in pg_publication.c, so that
would include RemovePublicationSchemaById().  If you do that,
GetSchemaPublicationRelations() could be local to pg_publication.c.

+   tup = systable_getnext(scan);
+   if (HeapTupleIsValid(tup))
+       result = true;
This can be written as just "result = HeapTupleIsValid(tup)".  Anyway,
this code also means that once we drop the schema this publication
won't be considered anymore as a schema publication, meaning that it
also makes this code weaker to actual cache lookup failures?   I find
the semantics around pg_publication_namespace is bit weird because of
that, and inconsistent with the existing
puballtables/pg_publication_rel.
