I don't think that it's good idea to control that behavior by using
--status-interval. I'm sure that there are some users who both want
that behavior and want set the maximum interval between a feedback
is sent back to the server because these settings are available in
walreceiver. But your version of --status-interval doesn't allow those
settings at all. That is, if set to -1, the maximum interval between
each feedback cannot be set. OTOH, if set to the positive number,
feedback-as-soon-as-fsync behavior cannot be enabled. Therefore,
I'm thinking that it's better to introduce new separate option for that
behavior.
