[Qgis-user] Snap points to nearest line

 yes - this would work, but the drawback is that the triggers are only 
 triggered on saving the data and not when the snapping happens ... 
 Saving in QGIS only happens manually after a user clicked on the save 
 button or leaves the edit sesssion.

 It would be nice to have the option of immediate saves to PostgreSQL 
 for each edit of any single record, for such purposes.
