@ritchie46, FYI, I changed the definition of the dataset to help polars with
filtering the partitions like so
```python
ibpolar = dataset("install-base-from-vdw-standard/vehicle_type=536/",
filesystem=fs, partitioning="hive")
```
polars now used half of the memory compared to duckdb, and spent 7 seconds
vs 12 on duckdb.
So being able to push down filters on partition columns would help a lot.
