There are considerable benefits to having a standby registry with a

replication via UPDATE (or ALTER STANDBY) statements.
I think that using a system catalog for this is going to be a
non-starter, but we could use a flat file that is designed to be
machine-editable (and thus avoid repeating the mistake we've made with
postgresql.conf).
Yeah, that needs some careful design. We also need to record transient
information about each slave, like how far it has received WAL already.
Ideally that information would survive database restart too, but maybe
we can live without that.
