回溯整理 覆盖月份：2026-09 · 整理发布：2026-10-02 · 来源：Postgres Weekly 存档
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 9 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
19 的多事之秋：MERGE/SPLIT PARTITION 与 SQL/PGQ 属性图先后被回退，延期乃至「推迟到 2027 年春」的争论在邮件列表公开化——Tom Lane 直言对 SQL/PGQ「相当担心」，David Rowley 与 Bruce Momjian 也各自表态，是理解 Postgres 治理机制的活教材。月末 Beta 4 如期发布，pgEdge 与 Snowflake 梳理了 19 仍会交付的特性清单。对冲素材：Tom Lane 谈 30 年架构演进的长文、WAIT FOR 读己之写实测、Plan Advice 落地解读；冯若航发布 pgsql.cc。月末还报出一个可能丢失更新的 bug——宁可砍特性也要保可靠，是本月的注脚。
