parallel aggregation - Numeric is unsupported?

Hi

is it expected in this moment?

Table "public.foo"
Column │ Type │ Modifiers
════════╪═════════╪═══════════
a │ integer │

postgres=# \d foo2
Table "public.foo2"
Column │ Type │ Modifiers
════════╪═════════╪═══════════
a │ numeric │

postgres=# explain select sum(a) from foo;
QUERY
PLAN
════════════════════════════════════════════════════════════════════════════════════════
Finalize Aggregate (cost=76498.35..76498.36 rows=1 width=8)
-> Gather (cost=76497.93..76498.34 rows=4 width=8)
Number of Workers: 4
-> Partial Aggregate (cost=75497.93..75497.94 rows=1 width=8)
-> Parallel Seq Scan on foo (cost=0.00..69247.94
rows=2499994 width=4)
(5 rows)

postgres=# explain select sum(a) from foo2;
QUERY PLAN
══════════════════════════════════════════════════════════════════════
Aggregate (cost=179053.25..179053.26 rows=1 width=32)
-> Seq Scan on foo2 (cost=0.00..154053.60 rows=9999860 width=12)
(2 rows)

p.s. It great step forward - it looks pretty well
