Hm, yeah, looks like numeric_poly_deserialize is missing a required init_var() step. Slightly astonishing that this got through even minimal testing.
For the archives' sake: I could not reproduce this at default settings, because the aggregate calls don't get parallelized. But it fails fairly quickly with set parallel_tuple_cost = 0; set parallel_setup_cost = 0; set min_parallel_relation_size = 0;
