Postgis GeoJSON silent massive loss of precision with coordinates specified as string values

gistfile1.txt

This works as expected:

corp=> SELECT ST_AsText(ST_GeomFromGeoJSON('{"type":"Point","coordinates":[-48.23456,20.12345]}')) As wkt;
            wkt
---------------------------
 POINT(-48.23456 20.12345)

but this doesn't:

corp=> SELECT ST_AsText(ST_GeomFromGeoJSON('{"type":"Point","coordinates":["-48.23456","20.12345"]}')) As wkt;
      wkt
---------------
 POINT(-48 20)

It seems that when coordinates are provided as strings they are truncated to integers.
Significant and silent data loss!

I'd prefer that it "just work", but I'd much prefer an exception being thrown rather than the current silent data loss.

hi @timbunce I see the issue is because of this in liblwgeom/lwin_geojson.c

...
  if (iType == json_type_double)
    pt.x = json_object_get_double( poObjCoord );
  else
    pt.x = json_object_get_int( poObjCoord );
...

and the corresponding statement for pt.y and pt.z. I will get it fixed. Thanks for reporting this!
