pgpool + repmgr - who should be responsible for failover

[Mariel Cherkassky <mariel.cherkassky@xxxxxxxxx>]

I configured replication with repmgr on 2 postgresql 9.6.3 nodes. Both of those utilities can handle failover but I should let only one of them do it. So, I wanted to know who should be the one responsible for the failover and why ?

Thanks .
