    Description

      Hi,

      In JSON, the order of items should has no influence on the results; however, the following test case shows a counterexample:

      SELECT ST_ASTEXT(ST_GEOMFROMGEOJSON('{"type":"GeometryCollection","geometries":[]}')); -- GEOMETRYCOLLECTION EMPTY
      		 
      SELECT ST_ASTEXT(ST_GEOMFROMGEOJSON('{"geometries":[],"type":"GeometryCollection"}')); -- NULL
      		 
      SHOW WARNINGS; -- Warning	4038	Syntax error in JSON text in argument 1 to function 'st_geomfromgeojson' at position 18
