Possibly a better way to handle this concern is to make the second
parameter: min_standby_grace_period - the minimum time a query will be
given in which to execute, even if max_standby_delay has been reached or
exceeded.

Would that more directly address you concerns?

min_standby_grace_period (ms) SIGHUP
