    Description

      MIN and MAX do not preserve the GEOMETRY and create a LONGBLOB instead:

      CREATE OR REPLACE TABLE t1 AS SELECT MAX(POINT(1,1)) AS p;
      		 
      SHOW CREATE TABLE t1;


      CREATE OR REPLACE TABLE t1 AS SELECT MAX((SELECT POINT(1,1))) AS p;
      		 
      SHOW CREATE TABLE t1;

      Both return:

      +-------+---------------------------------------------------------------------------+
      		 
      | Table | Create Table                                                              |
      		 
      +-------+---------------------------------------------------------------------------+
      		 
      | t1    | CREATE TABLE `t1` (
      		 
        `p` longblob
      		 
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1 |

            There are actually no MIN and MAX operations for geometry.
            The result is fine. It just treats the underlying bytes as a binary array.
