Posting a new version of the patches, with the following updates:
- Added parallel-safety check for index predicate and added extra
tests for this.
- Removed fix for query rewriter hasModifyingCTE bug and instead
handle this by detecting a modifying CTE within the parallel-safety
checks (and returning UNSAFE if one is found).
- Updated registration of parallel-safety-checked partition OIDs as
plan dependencies (only do it for parallel plans).
- Integrated parallel_dml patch.
