Snippet:
$ /build/build-test/debug/parquet-reader --only-metadata /tmp/pqfuzz/pq-table-1
...
Column 5: col_6 (FIXED_LEN_BYTE_ARRAY(11) / Decimal(precision=24, scale=7) / DECIMAL(24,7))
Column 6: col_7 (FIXED_LEN_BYTE_ARRAY(18) / Decimal(precision=43, scale=7) / DECIMAL(43,7))
...
Column 5
Values: 375, Null Values: 74, Distinct Values: 0
Max (exact: true): 98505381700645007.0205463, Min (exact: true): -99708959786297168.1726196
Compression: UNCOMPRESSED, Encodings: PLAIN(DICT_PAGE) RLE_DICTIONARY
Uncompressed Size: 3754, Compressed Size: 3754
Column 6
Values: 375, Null Values: 69, Distinct Values: 0
Max (exact: true): Parquet error: Failed to parse decimal value: Length of byte array passed to Decimal128::FromBigEndian was 18, but must be between 1 and 16
...This should be relatively easy to fix, as we can just use Decimal256 instead of Decimal128 when displaying statistics.
