Greetings all!

I have a problem with pgpool-ii-1.3.  Debug information is below...

I wish to deploy master-slave configuration with two backends (replication
with Slony-I). Pgpool-ii works on the backend0 ( master ).
Here is my configuration file:

listen_addresses = '*'
port = 9999
pcp_port = 9898
socket_dir = '/tmp'
pcp_socket_dir = '/tmp'
backend_socket_dir = '/tmp'
pcp_timeout = 10
num_init_children = 12
max_pool = 1
child_life_time = 300
connection_life_time = 0
child_max_connections = 0
authentication_timeout = 60

# logging
logdir = '/var/log'
print_timestamp = true
log_statement = true
log_connections = true
log_hostname = true
# End of logging

# Work mode
parallel_mode = false
replication_mode = false
load_balance_mode = true
master_slave_mode = true
# End of the work mode

reset_query_list = 'ABORT; RESET ALL; SET SESSION AUTHORIZATION DEFAULT'
connection_cache = true
health_check_timeout = 20
health_check_period = 0
health_check_user = 'nobody'
insert_lock = false
ignore_leading_white_space = false
enable_query_cache = false
pgpool2_hostname = 'replica.test.box.ru'
backend_hostname0 = 'replica.test.box.ru'
backend_port0 = 5432
backend_weight0 = 1
backend_hostname1 = 'replica1.test.box.ru'
backend_port1 = 5432
backend_weight1 = 1
enable_pool_hba = true


postgres at replica:~/bin$ ./psql -U tester -d testdb -W -p 9999 -h
192.168.157.120
Password for user tester:
psql: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.

In the debug information I got ERROR: pid 29857: pool_read_int: data does
not match between between master(0) slot[1] (50331648).
Any ideas?
Thank you in advance.
