将逻辑解码输出插件限制为新服务器参数 output_plugin_libraries 指定的集合（Jacob Champion）§ §

\n

此前，复制用户可以为逻辑解码选择任意可加载库，从而实施各种攻击。为了在不破坏原有可用配置的情况下收紧这一限制，现引入一份允许使用的输出插件列表。

默认情况下，只有随 PostgreSQL 提供的输出插件（pgoutput 和 test_decoding）会包含在 output_plugin_libraries 中。使用其他输出插件的安装必须在更新服务器后将其加入该参数，例如：

\n
output_plugin_libraries = 'pgoutput, test_decoding, my_trusted_decoder'\n

修复 contrib/pgcrypto 的 PGP 加密，使其能够检测不受支持的密码算法（Daniel Gustafsson）§ §

\n

此前，如果 OpenSSL 拒绝所请求的密码算法（例如，因为它正以 FIPS 模式运行，或尚未加载 legacy provider），pgcrypto 无法发现这一失败，只会将未经加密的块与明文进行异或，使这种“加密”轻易即可破解。这通常发生在已弃用或不符合 FIPS 的密码算法上（cipher-algo=blowfish/bf、twofish、cast5 或 3des）。

\n

默认情况下，pgcrypto 现在将无法解密以这种方式受影响的任何消息。为了能够取回这类数据，现新增选项 ignore-cipher-failure，用于 pgp_pub_decrypt() 和 pgp_sym_decrypt()。设置 ignore-cipher-failure=1 将恢复此前的行为，从而可以移除有缺陷的加密封装：

\n
pgp_sym_decrypt(encrypted_column, any key, 'ignore-cipher-failure=1')\n
\n

识别出受影响的消息并移除其封装后，即可使用现代算法重新加密。不过，OpenSSL 的行为必须与创建这些有缺陷消息时相同：如果不受支持的算法集合并不相同，这种方法将无法奏效。请参阅 ignore-cipher-failure 的文档。

修复 psql：跳过脚本中的 COPY ... FROM STDIN 命令后面的内联数据，即使 COPY 在发送 PGRES_COPY_IN 前失败（Tom Lane）§ §

\n

此前，如果 COPY 命令在开始执行时失败（例如目标表不存在）， psql 无法意识到这一点，会继续把随后的内联数据当作 SQL 命令读取。即使在最好的情况下这也是错误的，在最坏的情况下则会构成 SQL 注入风险。现在，psql 会识别语法有效的 COPY ... FROM STDIN 命令，并在服务器没有返回 PGRES_COPY_IN 时自行跳过数据。

\n

此修复不太可能影响生产 SQL 脚本，但测试脚本可能会有意测试失败的 COPY ... FROM STDIN 命令。此类脚本需要在每条这样的命令后增加一行 \\. 数据终止符。
