[Tfug] synchronizing databases (postgres)

[Jeremy C. Reed]

Can anyone point me to some docs or suggest some ideas or tools (like perl 
modules or scripts) for synchronizing postgres databases?

I will be migrating data from one server to another but may take several 
days. I am researching to see if I can keep the existing server up and 
available. And after the migration just turn the user interface off and do 
a quicker "sync" of the two databases to complete the migration. (With the 
hope that the downtime will be less than a couple hours instead of couple 
days.)

Any advice would be appreciated.
