Hi, i'm really new to postgresql replication, was there any
replication tool for postgresql that can do real-time replication from
1 database to ~3-10 database (on the other machines) with little
overhead for load balancing purpose?

Well, you're not telling us how much traffic you're looking at or how
powerful your servers will be. Where I work we have two large master
servers (lots of SAS drives on power hardware RAID controllers with
battery backed cache) which are our master and slave-master, so to
speak, then we currently have two, but may have more, slaves synced
off of the slave-master machine. We use slony. It works well enough,
but there are some issues with large numbers of db objects (lots of
tables / indexes / schemas) that we've run into with it that are
making me pull some hair out, and I haven't had time to troubleshoot
them.
Overall though, it's a quite capable system, and once it's setup and
running it's fast and stable.
There's also londiste, bucardo, and a few others worth looking at.

If, by "real time", you mean that a tuple created or changed on the
master is visible to queries on an arbitrary slave within a few
seconds, then Bucardo and Slony are both good candidates. I've used
Bucardo in just such an environment, along with its master-master
capability. Of the two, I definitely prefer the former, but this
isn't an advocacy list, and they both work.
The amount of overhead you'll experience is a function of how "chatty"
your data is -- the higher the volume of changes it needs to
replicate, the more work it will take to keep those changes flowing
out to the slave nodes. If you update the same tuple three times in a
five second period, that's three tuples you'll be replicating out to
each slave.
Another important consideration is the size of your replication sets
(in Slony terms; "herds" in Bucardo). The bigger they are -- the more
tables they include -- the more work it will take to replicate any
changes in any of their member objects. IME, you'll typically do well
to keep your sets down to the smallest meaningful groups you can.
Particularly, you'll want to group together tables that are
interrelated by foreign keys (this is especially important if you're
using Slony, and have any plans to support switching masters), or that
you expect to be modified together -- for example, all the tables that
might be modified in the course of a new order being entered into your
OLTP application.

Hi,
probably pgpool-II is worth trying. A new version has been released two days
ago....

My prefered asynchronous replication solution for PostgreSQL is Londiste
from Skytools, don't miss its tutorial:

Hi,
If it is an async. replication, then I would look no further than PostgreSQL’s native streaming replication functionality.

Hi,
If it’s a multi-master then you are better off with one of those tools. I am sorry, I can’t recommend any from the two because I haven’t used either of them. Although, I have used slony which is complicated to setup but very robust to break.
