3.4. Configuring authentication in pg_hba.conf

Ensure the repmgr user has appropriate permissions in pg_hba.conf and can connect in replication mode; pg_hba.conf should contain entries similar to the following:

    local   replication   repmgr                              trust
    host    replication   repmgr      127.0.0.1/32            trust
    host    replication   repmgr      192.168.1.0/24          trust

    local   repmgr        repmgr                              trust
    host    repmgr        repmgr      127.0.0.1/32            trust
    host    repmgr        repmgr      192.168.1.0/24          trust
  

Note that these are simple settings for testing purposes. Adjust according to your network environment and authentication requirements.
