I dug a bit further and had reasonable success adding two new stats into 
status_detail:

- Data Rate (insert/delete/truncate/conflict) per second

- Replication Lag

I pushed the code here: 
https://github.com/miketonks/bucardo/commits/status-extras


I'm not certain the lag time is measured correctly.  If bucardo is 
stopped then the most recent delta should give a good metric, but if 
bucardo is running I'm not sure how to do this.

Also the lag time requires a connection to each node, which could be 
slow if any connection times out.  Can anyone suggest a way around this?

Any feedback appreciated.

Thanks,
