Windows allows unsigned 32Bit exit codes which are larger than the smallint type of int_exit_status.
We could change the type of int_exit_status to INTEGER but since postgres only has signed integers this would mean that we could still only represent half of the exit codes.
The other option would be BIGINT but thats 8bytes which would be a lot of storage.
