Hi all,

I'm with a problem and have no idea how may I fix.

I'm trying to install a pgpool-II to be only a connection pool (not
replication, master slave...), only connection pool.

When I try to connect to database directly by the port of database, it
works, but when I try to connect by the port of a pgpool it does not
work.

Enviorement:
Debian 6
Postgresql 9.3
pgpool-II 3.3.1-1.pgdg60+1
