Yes, this is true that it can cause service disruption, but the same will be
True even if master detects that internally by having timeout.
By keeping this as external, the current behavior of PostgreSQL can be
maintained that
if there is no standy in sync mode, it will wait and still serve the purpose
as externally it can send message for master.
