Wrong node name for "Hash join"

[ioguix]

Hello,

Considering this query:

DROP TABLE IF EXISTS bebe, ahah;

CREATE TABLE ahah (c1 serial PRIMARY KEY, c2 integer);
INSERT INTO ahah (c2) SELECT generate_series(2000, 3000);

CREATE TABLE bebe (c1 serial PRIMARY KEY, c2 integer);
INSERT INTO bebe (c2) SELECT generate_series(2000, 3000);
ANALYZE;

EXPLAIN (ANALYZE, BUFFERS, COSTS OFF)
SELECT ahah.c1, max(ahah.c2), max(bebe.c2)
FROM bebe
JOIN ahah
ON bebe.c1 = ahah.c1
GROUP BY ahah.c1;

Here is the plan:

 HashAggregate (actual time=6.004..7.028 rows=1001 loops=1)
   Group Key: ahah.c1
   Buffers: shared hit=10
   ->  Hash Join (actual time=1.626..4.086 rows=1001 loops=1)
         Hash Cond: (bebe.c1 = ahah.c1)
         Buffers: shared hit=10
         ->  Seq Scan on bebe (actual time=0.039..0.502 rows=1001 loops=1)
               Buffers: shared hit=5
         ->  Hash (actual time=1.558..1.559 rows=1001 loops=1)
               Buckets: 1024  Batches: 1  Memory Usage: 48kB
               Buffers: shared hit=5
               ->  Seq Scan on ahah (actual time=0.029..0.508 rows=1001 loops=1)
                     Buffers: shared hit=5

Pev2 shows "Hash" instead of "Hash Join".
