Oh, and an extensive existing Slony structure for some portions of the database. I could conceivably construct Slony sets for the currently non-replicated tables and iteratively subscribe them (so the initial subscribe doesn't take a week ...). I'm not at all sure Slony could keep up with our update load, though, especially not while maintaining current database operations and also handling those subscriptions. Slony doesn't really work well with high transaction volumes, in my experience. I am going to play with this and see where it breaks, but it's going to be an enormous time investment to babysit it. -- Alan
