problema recolector de estadisticas

Hola, compile la version 8.1.4 en un sistema ubuntu.
Todo iba bien, pero cuando le active el autovacuum aparecio los
siguiente en el log:

2006-08-29 12:50:20.039 CDTLOG: could not receive test message on
socket for statistics collector: Connection refused

En el postgresql.conf tengo:

listen_addresses= '*'
max_connections = 100
superuser_reserved_connections = 4
log_rotation_size = 2000
log_line_prefix = '%m'
stats_start_collector = true
stats_command_string = true
stats_block_level = true
stats_row_level = true
autovacuum = on
lc_messages = 'es_MX.UTF-8'

lc_monetary = 'es_MX.UTF-8'
lc_numeric = 'es_MX.UTF-8'
lc_time = 'es_MX.UTF-8'

Y pues no se si tenga que darle algun permiso a alguna cosa...

De antemano, gracias.

Alejandro
