Tell that to the DBA.  I bet s/he knows what "all standbys" means.
The fact that the system doesn't know something doesn't make it
unimportant.

I agree that we don't absolutely need standby registration for some
really basic version of synchronous replication.  But I think we'd be
better off biting the bullet and adding it.  I think that without it
we're going to resort to a series of increasingly grotty and
user-unfriendly hacks to make this work.
