    Description

      JSON histograms turn out invalid if a column value contains, for example, a double quote mark.

      create or replace table t (a varchar(32));
      		 
      insert into t values ('this is "quoted" text');
      		 
      set histogram_type= JSON_HB;
      		 
      analyze table t persistent for all;
      		 
      select * from t where a = 'foo';
      		 
       
      		 
      # Cleanup
      		 
      drop table t;
