That's exactly what I'd expect if the setting were coming from postgresql.conf, so I think you need to look harder. Are you sure you are looking at the right copy of postgresql.conf (check "show config_file" to be sure)? Maybe it's in some file included by postgresql.conf? What about postgresql.auto.conf? regards, tom lane
