In Postgres-R, I mostly use the terms 'local' and 'remote'.

Note that those terms only make sense if you limit yourself to thinking the master is pushing data out to the slave...

I think it'd make the most sense if the name reflected whether the trigger should be fired by a replication process or not; that way it doesn't really matter if it's a master or a slave... if the data in the table is being modified by a replication process then you don't fire the trigger/rule, according to the setting. But maybe there is some need to discern between origin and target...

That's why I prefer "origin" and "replica". I want to use the same terms in the sessions mode GUC, and there "local" could be misinterpreted as "doesn't replicate at all".

I will need that "local" mode anyway for some conflict resolutions. Think of a duplicate key (yeah, yeah, what comes now sounds bad ...) conflict, where you need to delete one of the entries without causing that delete to replicate.

Before people panic, the final system is supposed to have something smarter than deleting a dupkey in its repertoire. But I'll rather go with this cheap shot first and add a group communication based advisory locking system later, you know?
