Comment:
This could be an error because the code try to raise an exception.
-- Check if any edge crosses this node
-- (endpoints are fine)
--
FOR rec IN EXECUTE 'SELECT edge_id FROM '
|| quote_ident(atopology) || '.edge '
|| 'WHERE ST_Crosses(' || quote_literal(apoint::text)
|| ', geom)'
LOOP
RAISE EXCEPTION
'An edge crosses the given node.';
END LOOP;
I don't know why this exception don't raise.
however change from enhancement to defect the ticket.
