ST_RemoveIsoNode does not throw an exception when passed a non-existent node

[robe]

I can run this over and over again and get the same message:

SELECT topology.ST_RemoveIsoNode('ma_topo',  7 ) As result;

result

---

Isolated node 7 removed

I guess its isolated if it doesn't exist.

A non-existent node is surely removed.

This result is compliant with the description of the ST_RemoveIsoNode. And the node is isolated because as say the 2.c rules of draft there isn't any edge having it has start_node or end_node.

So I think the result is correct.
