I'll have to defer to the Slony folks on that one.

I mean complete step-to-step, as in exactly what you click and enter. I've
done what is at least on the surface the same thing you have, with no
problems. So there must be somethign in the details.

Part of it may - I don't recall offhand it the must-unsubscribe-first is a
rqeuirement of Slonik or just of pgAdmin.

It shuold be ok. pgAdmin currently has the concept of an "admin node" which
isn't compatible with the way core slony/slonik does it, but it shouldn't
actually be causing you any problems. Some very minor functionality (some
discovery) will not work in pgadmin if yo uset the cluster originallyi from
slonik, but managing the servers that you've got shouldn't be a problem a
And it's certainly the design goal - pgadmin shouldn't be doing anything
that breaks "the core slony way".
