Hi everyone,

Here's another crash caught by sqlsmith.

"""
drop table if exists fkpart3_pk5 cascade;
drop table if exists inet_tbl;

create table fkpart3_pk5 (
a integer not null primary key
)
partition by range (a);

create table fkpart3_pk51 partition of fkpart3_pk5
for values from (4000) to (4500);

create table inet_tbl (
c cidr,
i inet
);

select
1 as c0
from
(select null::integer as c9,
ref_0.a as c24
from fkpart3_pk5 as ref_0
) as subq_0
right join public.inet_tbl as sample_0 on (cast(null as cidr) = c)
where subq_0.c9 <= subq_0.c24
"""

Attached the backtrace.
