Is it normal to use the geometry type 'multipoint' instead of 'point' knowing that I use it to store only one point. How can I convert from multipoint to point

For convert "Multipoint" to "Point", you have to use ST_Dump, for example:

SELECT (ST_Dump(the_geom)).geom AS the_POINT_geom

On the question about use "Multi" o single geometries, I use this logic:

  • if every geometry has different attributes -> Single
  • if a group of geometries have same attributes -> "Multi"
