[Pgpool-general] Hello!!!

[Lazaro Ruben Garcia Martinez]

Hello everyone , Primarily excuse me because I don't know speak English very well.
I have a problem but I don't know how resolve it. I need to connect two nodes because I need to replicate the information, but when I tray to connect to the server an error occurs, I'm using pgpool-2.3.3, postgreSQL 8.3.3, and CentOS as Operating System.

I write: 
 /usr/bin/psql -h 192.168.101.121 -p 9999 -U pgpool2 -d postgres

the error is:
 error:psql: el servidor ha cerrado la conexión inesperadamente,
        probablemente porque terminó de manera anormal
        antes o durante el procesamiento de la petición.

The configuration in pg_hba.conf is:

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         all                               ident sameuser
# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
host    all         pgpool2     192.168.101.121/32      trust
