我正在嘗試在go-pg庫中為 golang使用.UnionAll方法。    var model []Customer    q0 := db.Model(&model).Where("name = ?", name0).Limit(4)    q1 := db.Model(&model).Where("name = ?", name1).Limit(3)    var result []Customer    if err := q0.UnionAll(q1).Limit(1).Select(&result); !as.NoError(err) {        return    }此代碼生成查詢：(SELECT "customer"."id", "customer"."name" FROM customers AS "customer" WHERE (name = 'customer 1deificatory zonoid reprepare alacrify serenissime') LIMIT 1) UNION ALL (SELECT "customer"."id", "customer"."name" FROM customers AS "customer" WHERE (name = 'customer 2fordless ferroboron radiability dandizette smutch'LIMIT 3))但我希望它是：(SELECT "customer"."id", "customer"."name" FROM customers AS "customer" WHERE (name = 'customer 1deificatory zonoid reprepare alacrify serenissime') LIMIT 4) UNION ALL (SELECT "customer"."id", "customer"."name" FROM customers AS "customer" WHERE (name = 'customer 2fordless ferroboron radiability dandizette smutch')LIMIT 3)LIMIT 1那么如何使用 go-pg 來獲取我期望的原始 SQL 查詢呢？問題是由于某種原因我不能將Limit 1表達式應用于整個查詢。另外，我的第一個成員Limit 4沒有正確應用。union all我的整個代碼在這里。
