What i tried before was to access (in PlanForeignModify) the RelOptInfo

It should work ... *if* there was in fact a RelOptInfo worked on
earlier. There sometimes isn't. You might need to do something like
what make_modifytable() has to do to call you in the first place:
Sorry for the late feedback, didn't manage to get back to this earlier.
This works indeed, the RelOptInfo structure stored in simple_rel_array (if
present) allows
a FDW to access its earlier scan state, assigned in GetForeignPlan() for
example.
Thanks for the hints!
