балансировщик нагрузки с использованием pgpool2 не работает, потоковая передача работает

Question

Я новичок в кластеризации postgres, я пытаюсь заархивировать балансировщик нагрузки с помощью pgpool2, но он не работает, выполните следующие шаги,

Это узлы:

мастернода, т.е. первичный 192.168.100.130, резервный сервер 192.168.100.131pgpool 192.168.100.132

Шаги:

      1. Installed postgresql-14 using below commands on all servers i.e. masternode, standbynode & pgpool.
2. Achived streaming on masternode and standby using below steps ; 
    Change in MasterNode :
        changes in /etc/postgresql/14/main/postgres.conf
            listen_addresses = '*'
            port = 5432

            wal_level = replica
            archive_mode = on
            archive_command = 'rysnc -a %0 /home/pg_wal_archive/%f'

        changes in /etc/postgresql/14/main/pg_hba.conf   
            host    all     all     192.168.100.131     trust
    
    Change in StanbyNode :
        removed files from main directory
        
        executed : pg_basebackup command.
        
    Streaming is working file, database and tables created at masternode are replicating standby node.
    
3. Installed pgpool2 on pgpool server note. postgres-14 is already installed here
    sudo apt install pgpool2
    
    
    listen_addresses = '*'
    port = 5432
    socket_dir = '/var/run/postgresql'
    listen_backlog_multiplier = 2
    serialize_accept = off
    reserved_connections = 0
    
    
    backend_hostname0 = '192.168.100.130'
    backend_port0 = 5432
    backend_weight0 = 0
    backend_data_directory0 = '/var/lib/pgsql/data'
    backend_flag0 = 'DISALLOW_TO_FAILOVER'
    backend_application_name0 = 'master'

                                       # walsender's application_name, used for "show pool_nodes" command
    backend_hostname1 = '192.168.100.131'
    backend_port1 = 5432
    backend_weight1 = 1
    backend_data_directory1 = '/data1'
    backend_flag1 = 'DISALLOW_TO_FAILOVER'
    backend_application_name1 = 'slave'

    log_destination = 'syslog'
    
    load_balance_mode = on
    ignore_leading_white_space = on
    
    
    master_slave_mode = on
    master_slave_sub_mode = 'stream'
    sr_check_period = 5
    sr_check_user = 'monitor'
    sr_check_password = 'Monitor@123'
    sr_check_database = 'postgres'
    delay_threshold = 0

    
Please check if I am missing something or do I missed any steps. Please note streaming is working as expected.
