When sync_client cannot connect to the replica, it enters a retry loop with
an exponential backoff between attempts.  This option sets the upper limit
on that exponential backoff: no matter how long the replica has been down
so far, sync_client will never wait longer than sync_reconnect_maxwait
between retries.

If this is zero or negative, the backoff duration will be allowed to
increase indefinitely (not recommended).

If no unit is specified, seconds is assumed.
