This reverts commits 6051857fc and ed52c3707 in HEAD (they were already reverted in the back branches). Further testing has shown that while those changes do fix some things, they also break others; in particular, it looks like walreceivers fail to detect walsender-initiated connection close reliably if the walsender shuts down this way. A proper fix for this seems possible but won't be done in time for v15.
