Solved!
The problem was in fact very simple. Because I'm in Debian, and installed postgresql the apt package manager, all configurations files was on /etc/postgres/8.3 etc... When I was trying to sync the two servers, I don't considerate that littles diferences beteween the server could be problematic. In fact, i've just copy all /etc/postgres/... from one server to another, start servers and pgpool and everything was working in replication mode. Just perfect as I wanted to :)

Thanks a lot for the help.

Hello Tatsuo,
I've just stop both of the postgresql services (docsys and docsys2), made a tar.gz of the data main directory send it (gziped) via scp to docssy2, start both services and pgtool.
Still not working... I really don't know why...

I can't really understand that... And the worst thing at the moment is thinking about online recovery if one the server goes down...

Thanks to all. Now I understand better how pgpool works.
Now I've been able to made some successful test. Replication Mode is working perfectly. The problem now is a little bit diferrent... I've just made a backup from the postgres production database, and freshly imported in two new databases in docsys and docsys2. The problem is when I try any kind of connection to pgpool (in 9999 port) I have the "kind mismatch error".

ex:
docsys:/home/rubenalves# /usr/lib/postgresql/8.3/bin/pgbench -i -h docsys -p 9999 imm_dbv12 -U postgres ERROR: kind mismatch among backends. Possible last query was: "SET search_path = public" kind details are: 0[C] 1[N]
HINT:  check data consistency among db nodes
server closed the connection unexpectedly
    This probably means the server terminated abnormally
    before or while processing the request.
docsys:/home/rubenalves#

I really can't understand because the both databases are IDENTICAL, how pgpool may find some differences?

Someone got an idea about this error?

You need to show us the log output with pgpool-II debug option
"-d".

Besides this, to make two databases "identical" by using
pg_dump/pg_restore is not enough for pgpool-II. pgpool-II requires two
database nodes "phyically identical". For this purpose you should use
tar/rsync or whatever tools to make a identical copy of database. In
your case probably you restore first database node by using pg_restore
then copy to second one by using tar or rsync.
