You can always skip all tests and insert the edges straight away, if
you know exactly what's expected as the structure. It will be faster.
You can then check with ST_ValidateTopology what's missing
(theoretically). That's what the TIGER loader does, for example, but
the input is already topological, no need to check.
My input data are already topological ( only lines are given ) so
inserting straight to table edge_data will work without noding and
checking for intersections
but what about next_left, next_right, etc pointers?
