修复 JIT 生成的元组解构代码中存储值的错误零扩展问题（David Rowley）§

不使用 JIT 时，等效代码执行的是符号扩展而非零扩展，导致小整数数据类型的 Datum 表示不同。这种不一致在大多数情况下被掩盖了，但已知在使用 Memoize 计划节点时会导致 “could not find memoization table entry” 错误，还可能存在其他症状。

为 TID Scan 和 TID Range Scan 计划节点添加缺失的 EvalPlanQual 重检查（Sophie Alpert，David Rowley）§ §

This was misguided, partially because non-concurrent DETACH doesn't do that, but mostly because in the case of hash partitioning the constraint expression contains references to the parent table's OID. That causes problems during dump/restore, or if the parent table is dropped after DETACH. In v19 and later, we'll no longer create any such copied constraints at all. In released branches, to minimize the risk of unforeseen consequences, only skip adding a copied constraint if it is for hash partitioning.", "commit_aliases": ["08c037dff", "3231fd045", "b753be38a", "b835759ec", "bdae98495", "ea06f97ee"], "source_commits": ["b753be38a"], "source_entry_id": "14.20/changes/014", "db_id": "417982fb5fc35be16b96cd9dffae86f4", "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f", "relations": [{"rule": 2, "type": "equivalent", "target": "565728557128822df30c43191a2dbfad", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}}, {"rule": 2, "type": "equivalent", "target": "71fe017c4d7b33e60357f0d6d3c24f44", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}}, {"rule": 2, "type": "equivalent", "target": "cf6c332f29166e2669260e45b57ff0d2", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}}, {"rule": 2, "type": "equivalent", "target": "d8002886e5e02df8376c5986e54462f2", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}}], "version": "14.20", "category_label": "其他改进", "also_in": [], "variants": [], "related_changes": [{"db_id": "565728557128822df30c43191a2dbfad", "kind": "equivalent", "version": "18.1", "label": "18.1", "title": "避免在 DETACH CONCURRENTLY 期间重复 hash 分区约束", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}, "url": "/docs/compare/?release=18.1#18.1-570dc654ef6dd9a2", "source_url": "/docs/release/18.1/#RELEASE-18-1-CHANGES"}, {"db_id": "d8002886e5e02df8376c5986e54462f2", "kind": "equivalent", "version": "17.7", "label": "17.7", "title": "避免在 DETACH CONCURRENTLY 期间重复 hash 分区约束", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}, "url": "/docs/compare/?release=17.7#17.7-7064942458440619", "source_url": "/docs/release/17.7/#RELEASE-17-7-CHANGES"}, {"db_id": "cf6c332f29166e2669260e45b57ff0d2", "kind": "equivalent", "version": "16.11", "label": "16.11", "title": "避免在 DETACH CONCURRENTLY 期间重复 hash 分区约束", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}, "url": "/docs/compare/?release=16.11#16.11-fe3f70460c985c25", "source_url": "/docs/release/16.11/#RELEASE-16-11-CHANGES"}, {"db_id": "71fe017c4d7b33e60357f0d6d3c24f44", "kind": "equivalent", "version": "15.15", "label": "15.15", "title": "避免在 DETACH CONCURRENTLY 期间重复 hash 分区约束", "evidence": {"same_day": true, "patch_ids": ["c7b7e5ea3577b3d900e06cd112a51878"], "statement_hash": "d5965bdd5734479eaa6212fe4307924b5fa45a4534d11494cdf8e41c2b84b97f"}, "url": "/docs/compare/?release=15.15#15.15-9c9de66bf89091ff", "source_url": "/docs/release/15.15/#ZH-AUTO-RELEASE-15-SECT2-6"}]}, {"id": "14.20-e39243838bbc984a", "cves": [], "html": "

以前，磁盘空间不足等失败会留下一个临时 state.tmp 文件。这是有问题的，因为它会阻止所有后续写入状态的尝试，需要手动干预来清理。
