BTW ... it occurs to me to ask whether we really have a solid use-case for having listeners attached to slave servers. I have personally never seen an application for LISTEN/NOTIFY in which the listeners were entirely read-only. Even if there are one or two cases out there, it's not clear to me that supporting it is worth the extra complexity that seems to be needed.
