<!-- Thank you for your contribution to Apache Cloudberry (Incubating)! --> Fixes #ISSUE_Number ### What does this PR do? <!-- Brief overview of the changes, including any major features or fixes --> This PR resolves critical issues with `pg_dump/pg_restore` for hash-partitioned tables using enum columns: 1. **Automatic root loading**: Auto-enables `--load-via-partition-root` when hash partitioning on enum columns is detected 2. **Parallel restore optimization**: Disables TRUNCATE during parallel restore in root-loading mode to prevent deadlocks and data loss 3. **Metadata marking**: Adds `-- load via partition root` comments to dump files for reliable identification 4. **Documentation cleanup**: Removes outdated warnings about root-loading + parallel restore incompatibility ### Type of Change - [ ] Bug fix (non-breaking change) - [ ] New feature (non-breaking change) - [ ] Breaking change (fix or feature with breaking changes) - [ ] Documentation update ### Breaking Changes <!-- Remove if not applicable. If yes, explain impact and migration path --> No breaking changes: 1. Hazard detection only activates for enum-based hash partitioning 2. Fully backward compatible with existing backup files 3. Serial restore behavior remains unchanged ### Test Plan <!-- How did you test these changes? --> - [ ] Unit tests added/updated - [ ] Integration tests added/updated - [ ] Passed `make installcheck` - [ ] Passed `make -C src/test installcheck-cbdb-parallel` ### Impact <!-- Remove sections that don't apply --> **Performance:** <!-- Any performance implications? --> **User-facing changes:** <!-- Any changes visible to users? --> **Dependencies:** <!-- New dependencies or version changes? --> ### Checklist - [ ] Followed [contribution guide](https://cloudberry.apache.org/contribute/code) - [ ] Added/updated documentation - [ ] Reviewed code for security implications - [ ] Requested review from [cloudberry committers](https://github.com/orgs/apache/teams/cloudberry-committers) ### Additional Context <!-- Any other information that would help reviewers?
