ft_reconnect_timeout

The amount of time (in seconds) that a standby server waits for clients to reconnect (after it becomes the active server in a failover situation).

ft_reconnect_timeout = seconds

If a client does not reconnect within this time period, the server removes its state from the shared state files. The ft_reconnect_timeout time starts once the server has fully recovered the shared state, so this value does not account for the time it takes to recover the store files.

The default value of this parameter is 60.
