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;

Thanks for the report!
