回溯整理说明：本页为 pgcn.cc 上线时（2026-10-02）对 Postgres Weekly 公开存档的 回溯性整理，覆盖 2026 年 2 月的社区动态；条目与日期来自原始存档， 内容归各原作者所有。本页并非当时发布的周报，周报自 2026 年第 1 期起按时发布。
本月脉络
本月看点是补丁节奏本身：2 月 12 日的例行小版本（18.2/17.8 等）引入回归，官方随即宣布 2 月 26 日临时加发（out-of-cycle）修复版，Percona 决定跳过该版、其发行版直接等 26 日修复版再出——升级窗口的取舍成了现成的风险管理案例。theconsensus.dev 的《Postgres 18 背后的公司》梳理了各公司对 18 的贡献，揭示商业力量分布。并发语义方面，行锁与 join 的意外结果、竞态条件的利用各有深读；recall.ai 关于 postmaster 成为高连接数瓶颈的一线经验、Hackorum 这个 pgsql-hackers 论坛化视图，都降低了旁观内核讨论的门槛。
