Looking at this list again, it strikes me that the listen/notify rewrite
might need to go in so that we have a sane framework for listen/notify
with HS. Treating pg_listener as a replicatable table isn't sane at
all, whereas with a message-driven notify mechanism we have at least got
the possibility of shipping the messages to the standby (via WAL) and
having listeners there. I don't want to say we'd actually implement
that in 8.5, but shipping pg_listener tuple updates is just completely
nuts.

The other four things have no apparent connection to HS/SR so I think
they could be punted without creating technical issues. Whether this
is really necessary from a schedule viewpoint is not clear yet.

My thought about it would be to put these four on the back burner;
not necessarily bounce them right away, but not put any effort into
them until we have dealt with the other stuff in the January CF.
At that point we should have a feel for where we are schedule-wise,
and in particular we'll know whether SR is in or not ;-)
