hello,
question about WAL on pg 9.0 :
the doc at http://www.postgresql.org/docs/9.1/static/warm-standby.html#SYNCHRONOUS-REPLICATION
(section 25.2.5.2. 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
standby.
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 ?
Cheers,
Ben-
