Dandandan opened a new issue #220:
URL: https://github.com/apache/arrow-datafusion/issues/220


   **Describe the bug**
   
   
   **To Reproduce**
   CREATE EXTERNAL TABLE csv (price INT) 
   STORED AS CSV
   LOCATION './tests/example.csv';
   
   `./tests/example.csv`:
   ```
   1
   2
   3
   ```
   ```sql
   CREATE EXTERNAL TABLE example (price INT) 
   STORED AS CSV
   LOCATION './tests/example.csv';
   > select * from example where 1=2 ;
   +-------+
   | price |
   +-------+
   | 1     |
   | 2     |
   | 3     |
   +-------+
   ```
   
   **Expected behavior**
   Should return an empty result set. When inspecting the optimized plan, the filter clause is removed (without changing the rest of the plan).
   
   **Additional context**
   The problem goes away when removing `FilterPushDown` so this is likely the offender
