server_timeout_server_connection

In a server-to-server connection, if this server does not receive a heartbeat for a period exceeding this limit (in seconds), it closes the connection. This parameter applies to connections from other routes and to the standby server connection.

server_timeout_server_connection = limit

We recommend setting this value to approximately 3.5 times the heartbeat interval of the other server. When the other server or the network are heavily loaded, or when client programs send very large messages, we recommend a larger multiple.

Note: In a fault-tolerant configuration, the server_timeout_server_connection parameter has no effect on the standby server following a failover. The standby server activates only after the timeout set by the ft_activation parameter.
