Does this change reuse code from several PostgreSQL commits, including 8eba3e3, 3db72eb, and 2ecbb0a, with additional generator changes from 62d712e, 5ac462e, and 27ee6ed?
Could you document these upstream references in the commit message and explicitly describe the adaptations for Cloudberry? Where possible, it would be preferable to cherry-pick the upstream commits with git cherry-pick -x to preserve the original authorship and provenance.

The generated _jumbleGpPolicy() hashes the attrs and opclasses pointer addresses instead of their contents. This makes identical CTAS statements produce different query IDs and splits their pg_stat_statements statistics. Reproduced on this PR: 20 identical CTAS executions produced two entries with calls = 1 and 19.

SHOW shared_preload_libraries;
