This view is unsafe because it doesn't schema-qualify its reference to table t. It will fail if run with a restrictive search_path, which is what pg_dump does for security reasons.
An ordinary view reference to "t" would be all right, because the system understands what that is and can adjust the schema qualification; but here you've just got a string that happens to contain "t" in it.
