As I mentioned earlier, yes it does work.

I also discovered by looking at all the postgres processes that it's making the first connection (to the master), but it doesn't seem to even try to make the second connection.

Could there be something else it's waiting for?  The dual-network issue may be completely irrelevant.  I know that while the IT guy was reconfiguring the network, he had to do a forced-reboot at least once without shutting down Postgres.  Is it possible that the Londiste tables are in some invalid state, and the daemon is waiting for something that's never going to happen?

Thanks,
Craig
