   THanks to @drauschenbach  for flagging this. I double checked and it works now
   
   ```sql
   DataFusion CLI v42.1.0
   > create table t as values ({a: 1, b:2}), ({a:2, b:3}), ({a:1, b:2});
   0 row(s) fetched.
   Elapsed 0.048 seconds.
   
   > select * from t;
   +--------------+
   | column1      |
   +--------------+
   | {a: 1, b: 2} |
   | {a: 2, b: 3} |
   | {a: 1, b: 2} |
   +--------------+
   3 row(s) fetched.
   Elapsed 0.009 seconds.
   
   > select column1, count(*) from t group by column1;
   +--------------+----------+
   | column1      | count(*) |
   +--------------+----------+
   | {a: 1, b: 2} | 2        |
