This infrastructure was added by commit 722408bcd1 and was only ever used
for publications and subscriptions.  Since we just bumped psql's minimum
supported version to v10, it's no longer used by anything.  Furthermore, a
quick glance indicates there's nothing else that should use it.  So, IMHO
we might as well remove it.
