Re: BUG #18260: Unexpected error: "negative bitmapset member not allowed" triggered by multiple JOIN

When I removed "window w0 as (partition by ref_33.c_3 order by
ref_33.c_4 desc)" in the test case query, the query did not trigger
errors any more.

Specifically, this query did not trigger errors:

with cte_1 as (select
    ref_1.c_0 as c_2,
    ref_1.c_4 as c_3,
    case when (nullif(ref_1.c_2, ref_1.c_0) <> (
          select
              ref_53.c_2 as c_0
            from
              (t1 as ref_52 left outer join t3 as ref_53 on true)
            where (ref_53.c_6) ~~ (ref_53.c_6)
            order by c_0 limit 1)
          ) then null else null end
         as c_4
  from
    t3 as ref_1)
select 1
  from
    cte_1 as ref_33
  where (ref_33.c_2 > (
        select
            ref_200.c_2 as c_0
          from
            t3 as ref_200
          order by c_0 limit 1));
