Reboot? Restart postgres? If you rebooted, you'll need to change the mode on /dev/dtrace/helper again, and the mode needs to be correct before postgres starts. You can set the mode in /etc/devfs.conf I guess, but ensure that the DTrace modules are already loaded when rc runs (i.e. by adding dtraceall_load="YES" to your loader.conf).
