    Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 AS SELECT NULL UNION SELECT POINT(1,1);
      		 
      SHOW CREATE TABLE t1;

      returns

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

      This is wrong. The expected column type is POINT.
