Structurally they are working in very different ways and I wouldn't have
thought that it would take much wind load to risk damaging the wall. This
might account for the lack of replies to your question.

This happened near me. The 3ft brick wall came down in one piece off its
raised plinth and fell onto the pavement. Luckily there was no-one
underneath.

can I guess the posts were attached to the wall tops with bolt down
met post things?

how high was the fence and what construction? panels, hit & miss ??

I would just forget the whole idea of fixing a fence to the wall. Railing
on top of a wall are fine as they put relatively little wind load on but a
fence, even a "hit and miss" design is a veritable sail.

Of course without pictures, dimensions or construction details of your wall
we're all guessing really.
