Howdy,

When calculating Replication lag, I know that we have to compare the 
pg_current_xlog_location
to pg_last_xlog_receive_location, etc. but what I'm trying to figure out is 
what are
the units that I'm left with after the calculation.

(i.e., does the xlog_location imply some time value?)

Here's the output of the (slightly modified script)
Master: 5003964876715
Receive: 5003964876715
Replay: 5003964765203

receive.value 0
apply.value 111512

111512 isn't inherently useful to me on its own.

Any tips?

Thanks

Dave
