The other possibility was it just didn't log the slower times, but I

in the 10,000 ms range in the night when some backups and housekeeping
happens.
All log related settings:
checkpoint_segments = 12
logging_collector = on
log_destination = 'stderr'
log_directory = 'pg_log'
log_filename = 'postgresql-%a.log'
log_truncate_on_rotation = on
log_rotation_age = 1440
log_rotation_size = 0
log_min_messages = info
log_min_error_statement = debug1
log_duration = on
log_line_prefix = '<%t>'
You might also want to log:
log_connections = on
log_disconnections = on
And add to log_line_prefix some mix of:
%u User name
%p Process ID
%s Process start time stamp
I know it does sound strange, but this is what we battled with for 2.5
days until the light
came on that the vacuum had been set to off on the target system during
server migration.
