trying to find non optimized queries and want to use this logging feature, however postgresql seems to write every query to log.
my conf is as follows
log_destination = 'csvlog'
logging_collector = on
log_directory = '/usr/local/pgb/pg_log'
log_rotation_size = 100MB
#syslog_facility = 'LOCAL0'
#syslog_ident = 'postgres'
#silent_mode = off
#client_min_messages = debug1
#log_min_messages = warning
#log_min_error_statement = error
log_min_duration_statement = 450
#debug_print_parse = off
#debug_print_rewritten = off
#debug_print_plan = off
#debug_pretty_print = on
#log_checkpoints = off
#log_connections = off
#log_disconnections = off
log_duration = on
#log_error_verbosity = default
#log_hostname = off
#log_line_prefix = ''
#log_lock_waits = off
#log_statement = 'all'
#log_temp_files = -1
#log_timezone = unknown
