I am using PostgreSQL 9.2.
I have installed xDB replication server through stack builder.
I want to know the how much the server slave is lag behind the master.
Master - 192.168.1.2 Slave - 192.168.1.3
If change in one of the table in master then it will synchronize the slave also but i want to know the how much bytes it is lagging behind ?
In steraming replication we can achieve through monitoring the table called pg_stat_replication and *_location column.
Is there any way in xDB replication server ?
