很慢我有這個非常簡單的查詢，通過我的ORM（實體框架核心）產生： SELECT *
FROM "table1" AS "t1"
WHERE EXISTS (
SELECT 1
FROM "table2" AS "t2"
WHERE ("t2"."is_active" = TRUE) AND ("t1"."table2_id" = "t2"."id"))
ORDER
我試圖創建以下索引; CREATE INDEX idx_concat_paostartno_paostartsuff ON
dmv_os_addbase_residential (concat(pao_start_number || pao_start_suffix));
我得到錯誤; ERROR: functions in index expression must be mark
我期待打印模式&所有模式中的物化視圖依賴關係的名字： select c.relname, d.classid, d.objid,
pg_describe_object(
d.classid, d.objid, d.objsubid)
from pg_class c
join pg_namespace n on c.relnamespace = n.oid
