Comment (by latot):

 Hi, here a simpler version I found today

 select ST_ConcaveHull(
         ST_COLLECT(
                 array[
                         'POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))'::geometry,
                         'POLYGON((0 0, 1 0, 1 1, 0 1, 0 0))'::geometry
                 ]
         ),
         0
 );

 Also postgis 3.4.
