In your postgresql.conf file you've got one of these turned on:

# - Statistics Monitoring -

#log_parser_stats = off
#log_planner_stats = off
#log_executor_stats = off
#log_statement_stats = off

just set it to off and reload.

I already tried it:

r3systems:~# grep log_ /home/postgres/data/postgresql.conf | grep stats

log_parser_stats = off
log_planner_stats = off
log_executor_stats = off
log_statement_stats = off

and that thinks still loggin in

r3systems:~# tail -n20 /home/postgres/logs/2008/02/2008-02-12_server.log

Any other ideas ?
