WordPress 7.1重构后台列表表格HTML，将复选框列从`<th>`改为`<td>`，文章标题列升级为`<th>`并加`aria-label`，以提升无障碍访问。此变更可能影响依赖旧结构的插件，需更新CSS/JS选择器适配，普通用户和前端无影响。

本文介绍HAProxy规则引擎（ACL）在数据面的位置与副作用。核心要点：规则按相位（连接、内容、HTTP请求）顺序求值，动作有副作用，顺序即语义；use_backend是有序内容交换，选中后仍有LB/队列；track与reject/deny的相对顺序影响限流计数；内容规则可反复求值，需注意性能；与stick-table耦合实现跨段状态共享。

HAProxy的stick-table机制同时支持会话粘滞和跟踪计数，其记忆能力由键类型、大小、过期时间和存储列共同定义。表满和过期是显式失败模式，分别导致限流变松和粘滞丢失。nbthread共享表，而nbproc不共享，多进程下全局限流语义会破裂。Peers与reload继承用于对齐多节点决策状态，与FD交接不同。存储列与键空间对齐决定跨代理标记是否生效，热路径写共享表有性能成本。

Phases 1-3 built the storage primitives — vectors, row groups, column segments, and compression. But there’s no concept of a “table” yet. There’s no way to define a schema (CREATE TABLE), no way...

PostgreSQL's table access method interface lets you plug in alternative storage engines.

Phase 1 gave us pages and heap files (raw byte storage on disk). Phase 2 gave us schemas and serialization (typed values to/from bytes). But these two layers don’t know about each other — you’d...

PostgreSQL's Table Access Method API is finally seeing real action.

When everyone has access to the same AI models, the winners are those who use them to build advantages that competitors can’t copy.

最近，一位客户的数据库表的auto_increment值接近最大容量。为避免超限，建议将数据类型从INT UNSIGNED更改为BIGINT。在使用pt-online-schema-change进行修改时，由于索引过大导致进程缓慢，最终决定取消该操作，采用Aurora蓝绿部署，直接在新集群上进行ALTER操作。通过删除次级索引后再添加，成功在auto_increment耗尽前完成了修改。此案例强调了监控auto_increment和合理规划的重要性。

Here is a GUC that ships with a warning label. The docs, which are normally restrained to the point of parody, state plainly that setting this parameter wrong can cause “irretrievable data loss or...

PDF table extraction often looks easy until it fails in production. Real bank statements can be messy, with scanned pages, shifting layouts, merged cells, and wrapped rows that break standard Java...

PostgreSQL 19 增加了 ALTER PUBLICATION 中对 EXCEPT TABLE 的支持，允许用户灵活地修改排除列表，从而更有效地管理表的发布和排除，提升了数据库的灵活性和可控性。

PostgreSQL 19将引入EXCEPT TABLE语法，允许用户在创建出版物时排除一个或多个表，从而避免将这些表的数据发送给订阅者。对于分区表，排除将在根级别应用，未来将支持通过ALTER PUBLICATION管理这些排除项。这一改进将增强逻辑复制的灵活性。
