Re: Live steraming replication setup issue!

Thanks Venkata, I am able to setup replication now. Just wondering when I check replication_delay and lag, I am getting negative number, any idea why?

receive | replay | replication_delay | lag
--------------+--------------+-------------------+-----
796/BA9D8000 | 796/BA9D7FF0 | -00:00:01.612415 | -2

Thanks,
Ashish

Can you consider putting recovery_target_timeline='latest' as well ? and can you help us know if you can see anything weird in the postgresql logfiles @ DR ?

Is DR in complete sync with the slave ?
