When will the variable (slots) in the synchronize_failover_slots() be freed?

[AikySay]

`static long
synchronize_failover_slots(long sleep_time)
{
List *slots;

// ... existing code ...

List *slots = remote_get_primary_slot_info(conn, pg_failover_slot_names_list);

// ... existing code ...

}`

When will slots be freed? Is there a risk of memory leak?
