I have one comment for the new error message.

+        case WORKERTYPE_UNKNOWN:
+            ereport(ERROR, errmsg_internal("should_apply_changes_for_rel: Unknown worker type"));

I think reporting an ERROR in this case is fine. However, I would suggest
refraining from mentioning the function name in the error message, as
recommended in the error style document [1]. Also, it appears we could use
elog() here.
