There is no such thing that i know. but the effect is the same as if
you shutdown the standby.
The problem is that if you have a standby server and stop walsender
and walreceiver. what happens when you start them again:
1) there would be accumalated work (wal records to send and to
receive), so it will take some time until standby catch up
2) what if the wal segment that was being used when you stopped
walsender is reused in master before walsender is reactivated?
