Wrong results with right-semi-joins

I ran into $subject and it can be reproduced with the query below.

create temp table tbl_rs(a int, b int);
insert into tbl_rs select i, i from generate_series(1,10)i;
analyze tbl_rs;

set enable_nestloop to off;
set enable_hashagg to off;

select * from tbl_rs t1
where (select a from tbl_rs t2
where exists (select 1 from
(select (b in (select b from tbl_rs t3)) as c
from tbl_rs t4 where t4.a = 1) s
where c in
(select t1.a = 1 from tbl_rs t5 union all select true))
order by a limit 1) >= 0;
a | b
---+---
1 | 1
(1 row)

The expected output should be 10 rows, not 1.

I've traced the root cause to ExecReScanHashJoin, where we neglect to
reset the inner-tuple match flags in the hash table for right-semi
joins when reusing the hash table. It was my oversight in commit
aa86129e1. Attached is patch to fix it.

Thanks
