Division on Integers
When computing division on integers, PostgreSQL performs integer division, while DuckDB performs float division:  
```sql
SELECT 1 / 2 AS x;
```  
PostgreSQL returns:  
```text
x

0
(1 row)
```  
DuckDB returns:  
|    x |
| ---: |
|  0.5 |  
To perform integer division in DuckDB, use the `//` operator:  
```sql
SELECT 1 // 2 AS x;
```  
|    x |
| ---: |
|    0 |
