Deprecate pgr_CreateTopology in 3.8 · Issue #2750 · pgRouting/pgrouting · GitHub

New in version: 2.0.0
Reason for deprecation:

Example:

SELECT * INTO vertices
FROM pgr_extractVertices('SELECT id, geom FROM edges ORDER BY id');

Finally using the data stored on the vertices tables the source and target are filled up.

/* -- set the source information */
UPDATE edges AS e
SET source = v.id 
  -- , x1 = x, y1 = y   <-- any additional changes if needed
FROM vertices AS v
WHERE ST_StartPoint(e.geom) = v.geom;

/* -- set the target information */
UPDATE edges AS e
SET target = v.id 
  -- , x2 = x, y2 = y  <-- any additional changes if needed
FROM vertices AS v
WHERE ST_EndPoint(e.geom) = v.geom;
