uses for that, otherwise threads may get lost ).

2.- Try to avoid top-posting, it's not the style of the list ( or mine ).

I need to take a backup of this live DB every night for the previous day (i.e the backup script running on 07/07/2016 will take the backup of the DB for 06/07/2016). This backup will be then transferred to the backup DB server and will be inserted into that DB. From what I have read pg_dump is the solution (similar to export in oracle), do you think of any other approach to get to this objective, have you come across a script or something that already does this,

Your requirement is a bit 'understated'. I assume your problem is:

1.- You have a backup with a series of tables which get inserted WITH
a timestamp.
2.- At the end of the day you want to transfer the inserted data, and
only the inserted data, to another server and insert it ther.

If BOTH servers are postgres, you can do it easily with a series of
COPY commands easily. If the target one is not postgres I would use it
too, but pass the COPY data through a perl script to generate whatever
syntax the target DB needs ( I've done that to go from postgres to sql
server and back using freebcp, IIRC, on the sql server side )

You still can have problems IF you have updates to the tables, or
deletions, or <insert your favorite problematic operation here>. But
if you just have insertions, copy is easy to do.
