## Which issue does this PR close? - Closes #. ## Rationale for this change PostgreSQL array literals should be rendered using `ARRAY[...]` syntax when unparsing SQL. Without this, roundtripped PostgreSQL SQL can lose the dialect-specific array form and emit a plain bracketed array literal instead. ## What changes are included in this PR? - Added a dialect hook to indicate whether array literals should render as `ARRAY[...]`. - Enabled that behavior for `PostgreSqlDialect`. - Updated the SQL unparser to honor the dialect setting when rendering array expressions. - Adjusted the PostgreSQL roundtrip test to expect `ARRAY[1, 2, 3, 4, 5]`. ## Are these changes tested? Yes. The PostgreSQL roundtrip test in plan_to_sql.rs covers the array literal case and verifies the unparsed SQL now uses `ARRAY[...]`. ## Are there any user-facing changes? Yes. PostgreSQL SQL generated by DataFusion will now emit array literals in `ARRAY[...]` form instead of plain bracketed form.

## Which issue does this PR close? - Part of #21078. ## Rationale for this change The `branch-52` release work added the `52.5.0` changelog in #21407, and that changelog should also be present on `main`. ## What changes are included in this PR? This PR ports `dev/changelog/52.5.0.md` from #21407 onto `main`. Implementation note: I used `git cherry-pick -n` of the merged `branch-52` commit and kept only the changelog file, discarding the version and config changes that do not belong on `main`. ## Are these changes tested? This is a documentation-only chabge ## Are there any user-facing changes? Yes. The `52.5.0` changelog is now available on `main`.
