Description of the change
bitnami/postgresql-repmgr
Append env REPMGR_PRIMARY_VISIBILITY_CONSENSUS to repmgr_generate_repmgr_config()
Benefits
repmgr.conf - primary_visibility_consensus
When the primary becomes unavailable in a multi-node cluster, the standbys can consult each other to build a quorum about a failover. This is done by asking each standby about the time it last saw the primary. If a node’s last communication was very recent and later than the time the local node saw the primary, the local node assumes the primary is still available, and does not go ahead with a failover decision.
