I spent some time looking some more at this, and I believe all that needs
to be done is check for a PRAM node with a type of PARAM_EXTERN.

During planning the planner turns the Param into a Const during
eval_const_expressions_mutator.

If it's as simple as I think it is, I hope we can get this committed for 18.
If not, and a longer discussion is needed, a new thread can be started
for this.
