+ This parameter is useful in configurations where a node in recovery
+ needs to control the amount of time to wait for new WAL data to be
+ available. For example, in archive recovery, it is possible to
+ make the recovery more responsive in the detection of a new WAL
+ log file by reducing the value of this parameter. On a system with
+ low WAL activity, increasing it reduces the amount of requests necessary
+ to access WAL archives, something useful for example in cloud
+ environments where the amount of times an infrastructure is accessed
+ is taken into account.
