When the Primary changes, pgfailover terminates client connections, and they must reconnect. Connection parameters are specified via environment variables with the PGFAILOVER_ prefix: export PGFAILOVER_BIND_ADDRESS=":5432" export PGFAILOVER_SERVERS="postgres://repuser@pg0.example.com/database?sslmode=disable&connect_timeout=5 postgres://repuser@pg1.example.com/database?sslmode=disable&connect_timeout=5" ./pgfailover The server role (Primary/Standby) is checked using pg_is_in_recovery(), by default every 5 seconds (PGFAILOVER_INTERVAL), with the number of connection attempts controlled by the PGFAILOVER_ATTEMPTS environment variable (default: 1).
