One solution is "Slony" to replicate tables to another database.
Or you can use PITR do copy every WAL logfile to your second machine
and apply all changes as far as you have logfiles.

Uh? At least a replication with PITR is straightforward, some config
modifications, a script to archive the logfile, one to restore the
logfile and something to transfer the logfile to your other machine.
Basically, that should be all you need.
Not so long ago i created such a setup and the replication itself was
the easy part. It got much worse the time we had to integrate the
replication into RH cluster software.


Kind regards
