Hi, 
 
One of my client is facing one issue the with PostgreSQL . The details
are as follows . 
  
1 . PostgreSQL  version 7.4.8 is running on 2 Linux machine  . One
acting as a primary database server and another one is acting as a
fail-over (secondary)server . 
2. Primar & secondary servers are located at different locations 
2.  Using DBmirror utility to mirror the database from primary to
secondary . 
  
With above setup , the problem is , there is a 1 day delay between
primary and secondary in the synchronization . That menas , if a client
put a record in the primary , it will sync to the secondary with delay
of 24 hours . 
  
My question is , for above mentioned requirement , what is the currect
way to solve the problem . I would like to know Is there any other way
to solve this problem . 
  
My idea is to implement DRBD to mirror the database between primary and
secondary . But , i want to know can DRBD suite this requirement or not
. And , is there any limitation while using DRBD in a WAN environment . 
  
 Thanks & Regards, 
Shashi Kanth
