steps:

1. download the parquet files generated by the fuzzer from https://github.com/duckdb/duckdb-fuzzer/tree/main/fuzz_result_duckdb_file_readers/run_13732252459/main-981c7a8573b254f8efd6b71f764c5c3bd924a53d/parquet_multi_param_fuzzer

git clone --no-checkout git@github.com:duckdb/duckdb-fuzzer.git afl_repr
cd afl_repr
git sparse-checkout set --no-cone fuzz_result_duckdb_file_readers/run_13732252459/main-981c7a8573b254f8efd6b71f764c5c3bd924a53d/parquet_multi_param_fuzzer
git checkout

2. copy the sqllogic test to a local duckdb repo; update the paths in the file to point to the location where you downloaded the parquet files
   https://github.com/duckdb/duckdb-fuzzer/tree/main/fuzz_result_duckdb_file_readers/run_13732252459/main-981c7a8573b254f8efd6b71f764c5c3bd924a53d/parquet_multi_param_fuzzer/parquet_multi_param_fuzzer-981c7a8573b254f8efd6b71f764c5c3bd924a53d.test
