    SELECT * FROM read_csv('example.csv.xz');
  extended_description: |
    This extension adds file-level compression formats that DuckDB does not
    support natively. It integrates with DuckDB's virtual filesystem so
    compressed files can be used directly by readers and writers such as
    `read_csv` and `COPY`.

    Supported formats include LZ4 (`.lz4`), Snappy (`.sz` and `.snappy`),
    Brotli (`.br`), Bzip2 (`.bz2`), and XZ (`.xz`).
