testing pgpool

Hi list!!

I tested pgpool with pgpool.conf as follows:

listen_addresses = 'localhost'

port = 9999

socket_dir = '/tmp'

backend_host_name = ''

backend_port = 5432

backend_socket_dir = '/tmp'

secondary_backend_host_name = ''

secondary_backend_port = 0

num_init_children = 15

max_pool = 10

child_life_time = 300

connection_life_time = 0

logdir = '/tmp'

replication_mode = false

replication_strict = true

replication_timeout = 5000

load_balance_mode = false

weight_master = 0.5

weight_secondary = 0.5

replication_stop_on_mismatch = false

reset_query_list = 'ABORT; RESET ALL; SET SESSION AUTHORIZATION DEFAULT'

print_timestamp = true

master_slave_mode = false

connection_cache = true

health_check_timeout = 20

health_check_period = 0

health_check_user = 'nobody'

but when I try get internal status of pgpool (psql -p 9999 -c 'show pool_status' template1) I get:

psql: could not connect to server: ¸W(at)$g@¹#(at)xöÿ¿Q
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.9999"?

Thank's
