操作步骤
本单汇总 Ustore 加固测试中开发已确认的资料缺口(临时仓 #46/#47/#48)。请按条修订手册。
1)系统列 × Ustore(临时 #48)
CREATE TABLE t_cmin(id int) WITH (storage_type=ustore); INSERT INTO t_cmin VALUES (1); SELECT xmin, xmax, ctid FROM t_cmin; -- 可用 SELECT cmin, cmax FROM t_cmin; -- 报错不支持文档未给出「系统列 × 存储引擎」能力说明。
2)TABLESAMPLE 与 Ustore 分区表(临时 #46)
-- Ustore 堆表:TABLESAMPLE 可用 -- Ustore 分区表 / PARTITION() 扫描: SELECT count(*) FROM ts_part TABLESAMPLE BERNOULLI(50); -- ERROR: Ustore not support table sampling yetselect.mdTABLESAMPLE 写明表名可为分区表,未写 Ustore 分区表限制;错误串写成「Ustore」整体不支持采样,与堆表可用不符。3)ustore_attr 取值与 gs_guc(临时 #47,按开发复核口径)
ustore_attr布尔子键仅接受true/false(例如enable_ustore_partial_seqscan=true可 SET;=on会报 invalid),与普通布尔 GUC 接受 on/off 的习惯不一致,文档宜写清。ustore_unit_test)应在文档标注或移除。gs_guc对非法ustore_attr子键/值仍可能报 Success 并写入 postgresql.conf;reload 可能静默忽略,restart 可能导致实例无法启动——文档宜警示(或工具侧增加校验)。SET ustore_attr = 'enable_ustore_partial_seqscan=on'; -- invalid SET ustore_attr = 'enable_ustore_partial_seqscan=true'; -- 可成功实际输出
日志信息
临时仓 #46/#47/#48 开发已确认(#47 按复核口径修正,非原「虚列」表述)。本单为新开资料合集,不追加历史 docs#7300。
