question about WAL on pg 9.0 :

the doc at
(section Monitoring) says:

 You can calculate this lag by comparing the current WAL write
location on the primary with the last WAL location received by the

but the WAL values i get are not 177/13C4E158 , 177/13C52BC0 so how to
calculate the lag ? should i apply a basic hex conversion first ?
