add the following to /etc/rc.conf:

rc_local_need="postgresql-9.5"
(or whichever version you are currently using)

That will force "local" to be stopped before "xdm"

but as far as I am aware, the "local" service is normally started last and 
stopped first.
As long as it's stopped before postgresql, you should be fine.
