## Which issue does this PR close? - Closes #20273. ## Rationale for this change `DataFrame::describe()` builds min/max aggregates for non-numeric columns and then casts the results to `Utf8` for display. That works for strings, but it fails for unsupported binary-like outputs such as `FixedSizeBinary`, which currently causes describe to error instead of falling back to null summary values. ## What changes are included in this PR? - Treat `FixedSizeBinary` as an unsupported min/max describe type, alongside the other binary-like types that cannot be rendered through the current `Utf8` cast path. - Reuse the same type predicate for both min and max summary construction. - Add a regression test covering `describe()` on a `FixedSizeBinary` column. ## Are these changes tested? - `cargo test -p datafusion --test core_integration describe_fixed_size_binary -- --nocapture` - `cargo test -p datafusion --test core_integration dataframe::describe:: -- --nocapture` ## Are there any user-facing changes? `describe()` no longer errors on `FixedSizeBinary` columns; unsupported min/max summaries now fall back to `null` as intended. -- This is an automated message from the Apache Git Service.
