Thanks!

But whether MyWalSnd->write is InvalidRecPtr or not, if it's behind sentPtr,
walsender should keep waiting for the ack to all the sent message to be
replied, i.e., isn't this expected behavior of normal shutdown? That is,
if we want to shutdown walsender even when the client side doesn't
reply message, immediate shutdown should be used or the client side
should be terminated, instead?
