Query with window function, hstore condition and outer join causes segmentation fault

Running the following SQL query always causes SEGFAULT in Citus 13.1.0/13.1.1 with PG17.5.
Tthis issue seems similar to #7705, but SEGFAULT with both of HSTORE condition and OUTER JOIN.

Testing environment:

* Rocky Linux 9.5
* Postgres 17.5 (src)
* citus 13.1.0, 13.1.1
* 1 coordinator, 3 workers

Reproduce queries:
```
CREATE SCHEMA segfault_reproduce;

SET search_path TO segfault_reproduce,"$user",public;

DROP TABLE IF EXISTS segfault_reproduce.users CASCADE;
CREATE TABLE segfault_reproduce.users (
tenant_id VARCHAR(10) NOT NULL,
session_id TEXT NOT NULL,
customer_id TEXT,
personal HSTORE
);

SELECT create_distributed_table('users', 'session_id');
SELECT truncate_local_data_after_distributing_table('users');

DROP TABLE IF EXISTS segfault_reproduce.user_sessions CASCADE;
CREATE TABLE segfault_reproduce.user_sessions (
tenant_id VARCHAR(10) NOT NULL,
ts TIMESTAMP NOT NULL,
session_id TEXT NOT NULL
);

SELECT create_distributed_table('user_sessions', 'session_id');
SELECT truncate_local_data_after_distributing_table('user_sessions');
