[Wolf Schwurack]

First of all you don't put the password in pool_hba.conf this should 'trust, md5 etc. Password are encrypted in pool_passwd. If you read the documents it going over all of this

    Our firewall limits access to PostgreSQL from other networks to prevent applications from connecting to the individual instances rather than pgpool.

    My pg_hba.conf for PostgreSQL limits connections to the pgpool hosts. In this case the pgpool virtual IP is 192.1.213.40 and the 3 hosts are allowed to connect to PostgreSQL directly.

    hostssl all all 192.1.213.41/32 password
    hostssl all all 192.1.213.42/32 password
    hostssl all all 192.1.213.43/32 password
