PostgreSQL add hosts in db

Hello,

I configure the Kea DHCP with a postgresql database.

I configured to add lease in this database and it works

    "lease-database": {
        "type": "postgresql",
        "name": "dhcp",
        "user": "kea",
        "password": "toto",
        "host": "localhost",
        "port": 5432
     },

I configured also to add a host

    "hosts-database": {
        "type": "postgresql",
        "name": "dhcp",
        "user": "kea",
        "password": "toto",
        "host": "localhost",
        "port": 5432
    },

But I have nothing in my database after the connection of a new host

 host_id | dhcp_identifier | dhcp_identifier_type | dhcp4_subnet_id | dhcp6_subnet_id | ipv4_address | hostname | dhcp4_client_classes | dhcp6_client_classes | dhcp4_next_server | dhcp4_server_hostname | dhcp4_boot_file_name | user_context | auth_key

Do you have an idea ? I miss an element or I don't understand something ?

Thank you in advance,
