    Description

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (g GEOMETRY REF_SYSTEM_ID=101);
      		 
      DROP TABLE IF EXISTS t2;
      		 
      CREATE TABLE t2 AS SELECT g AS g_column, COALESCE(g) AS g_coalesce FROM t1;
      		 
      DROP TABLE IF EXISTS t3;
      		 
      CREATE TABLE t3 AS SELECT g AS g_union FROM t1 UNION SELECT g FROM t1;
      		 
      SELECT G_TABLE_NAME, G_GEOMETRY_COLUMN, SRID FROM INFORMATION_SCHEMA.GEOMETRY_COLUMNS;

      returns

      +--------------+-------------------+------+
      		 
      | G_TABLE_NAME | G_GEOMETRY_COLUMN | SRID |
      		 
      +--------------+-------------------+------+
      		 
      | t1           | g                 |  101 |
      		 
      | t2           | g_column          |  101 |
      		 
      | t2           | g_coalesce        |    0 |
      		 
      | t3           | g_union           |    0 |
      		 
      +--------------+-------------------+------+

      Notice, g_column preserved the original REF_SYSTEM_ID, which is correct.
      More complex cases (e.g. g_coalesce and g_union) did not, as they should.
