避免在使用 PAM 认证时记录有关已放弃连接的报错消息（Tom Lane）

\n

基于 libpq 的客户端在需要密码时通常会尝试连接两次，因为它们直到第一次连接尝试失败后才会提示用户输入密码。因此，服务器在客户端收到密码请求后关闭连接时，不会生成无用的日志消息。然而，PAM 认证代码没有遵循这一约定，会为实际上并未发生的认证失败生成多条消息。

修复 bitshiftright() 的错误行为（Tom Lane）

\n

当位串长度不是 8 的倍数时，位串右移操作符未能将结果最后一个字节中的填充空间清零。虽然大多数操作看不到这些填充位，但其中任何非零位都会导致意外的比较行为，因为位串比较预期这些额外的位始终为零，并未特意忽略它们。

\n

如果由于将 bitshiftright() 的输出保存在表中而导致数据不一致，可以使用类似以下语句进行修复：

\n
UPDATE mytab SET bitcol = ~(~bitcol) WHERE bitcol != ~(~bitcol);\n

在 psql 中，意外丢失连接并成功重新连接后，重新同步关于服务器的内部状态（Peter Billen，Tom Lane）

\n

通常这并不必要，因为状态本来就是相同的。但在边界情况下可能有影响，例如连接可能指向多台服务器中的某一台。此更改使 psql 重新输出原本在启动时会输出的所有交互消息，例如是否使用 SSL。

修复 contrib/intarray 的 GiST 操作符类，使其在空数组上使用 <@ 时不会失败（Tom Lane）

\n

array_column <@ constant_array 这样的子句被认为可以使用索引，但索引搜索可能找不到空数组值；显然，这类条目应当直接匹配该搜索。

\n

唯一可行且能回补到旧版本的修复方法，是让 <@ 索引搜索扫描整个索引，本补丁正是这样做的。遗憾的是，这意味着查询性能很可能比普通顺序扫描还差。

\n

性能受到此更改不利影响的应用有几种选择。可以切换到没有此缺陷的 GIN 索引，也可以将 array_column <@ constant_array 替换为 array_column <@ constant_array AND array_column && constant_array。后者的性能与以前大致相同，并会找出给定常量数组的所有非空子集；这也正是以前能够可靠期望该查询做到的全部事情。

The only practical back-patchable fix for this requires making <@ index searches scan the whole index, which is what this patch does. This is unfortunate: it means that the query performance is likely worse than a plain sequential scan would be. Applications whose performance is adversely impacted by this change have a couple of options. They could switch to a GIN index, which doesn't have this bug, or they could replace array_column <@ constant_array with array_column <@ constant_array AND array_column && constant_array. That will provide about the same performance as before, and it will find all non-empty subsets of the given constant array, which is all that could reliably be expected of the query before.", "commit_aliases": ["113b3d903", "2f76f4182", "5b3e6c13f", "614119d00", "ced272d2d", "e519eded6", "efc77cf5f"], "source_commits": ["5b3e6c13f"], "source_entry_id": "10.11/changes/053", "db_id": "095d1b932d2c8b19ac2c80541fa441c9", "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e", "relations": [{"rule": 2, "type": "equivalent", "target": "1c9f43f55f1b5b56c782ba572b576692", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "3aca8549b51328708bd5a5bf23277edc", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "73e885c18b9f26670dcde44f3cce58b1", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}, {"rule": 2, "type": "equivalent", "target": "85ba616e74f33ab854bbdba4c2efb25a", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}}], "version": "10.11", "category_label": "BUG 修复", "also_in": [], "variants": [], "related_changes": [{"db_id": "3aca8549b51328708bd5a5bf23277edc", "kind": "equivalent", "version": "11.6", "label": "11.6", "title": "修复 contrib/intarray 的 GiST 操作符类，使其在空数组上使用 <@ 时不会失败", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=11.6#11.6-5ed18192f91e54e7", "source_url": "/docs/release/11.6/#id-1.11.6.21.5"}, {"db_id": "73e885c18b9f26670dcde44f3cce58b1", "kind": "equivalent", "version": "9.6.16", "label": "9.6.16", "title": "修复 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.6.16#9.6.16-059f1bbda100d67f", "source_url": "/docs/release/9.6.16/#id-1.11.6.13.5"}, {"db_id": "1c9f43f55f1b5b56c782ba572b576692", "kind": "equivalent", "version": "9.5.20", "label": "9.5.20", "title": "修复 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.5.20#9.5.20-059f1bbda100d67f", "source_url": "/docs/release/9.5.20/#id-1.11.6.10.5"}, {"db_id": "85ba616e74f33ab854bbdba4c2efb25a", "kind": "equivalent", "version": "9.4.25", "label": "9.4.25", "title": "修复 contrib/intarray 的 GiST 操作符类在空数组使用 <@ 时不失败的问题", "evidence": {"same_day": true, "patch_ids": ["a31fe9b8f8907f88284116f7ea7acc4a"], "statement_hash": "00dc80375dc59960aae1c99004068ad1481c61dfaff14bdf361701e252e9d80e"}, "url": "/docs/compare/?release=9.4.25#9.4.25-059f1bbda100d67f", "source_url": "/docs/release/9.4.25/#id-1.11.6.6.6"}]}, {"id": "10.11-dceb1e7c16b596f4", "cves": [], "html": "
