Is there a more advance way to handle Go Entgo postgreSQL error handling?
问题
所以我正在使用Go语言和ORM包Entgo以及Postgres开发API。是否有一种处理错误的方式，与pg包中解决查询失败的方式相同或类似，以便我可以获得所有必要的信息？
在ent go中，我找到了以下方法，但它们只返回布尔值：
ent.IsNotFound(err)
ent.IsConstraintError(err)
ent.IsNotLoaded(err)
ent.IsValidationError(err)
如果能够有类似pg.Error的东西就太好了：
type Error struct {
Severity string
Code ErrorCode
Message string
Detail string
Hint string
Position string
InternalPosition string
InternalQuery string
Where string
Schema string
Table string
Column string
DataTypeName string
Constraint string
File string
Line string
Routine string
}

So I'm developing a API using Go together with ORM package Entgo and Postgres. Is there a way to handle the errors same or similar way as they are solved in pg package where I have all needed information why query failed?
All I found in ent go are this methods but they only return bool
ent.IsNotFound(err)
ent.IsConstraintError(err)
ent.IsNotLoaded(err)
ent.IsValidationError(err)
It would be great to have something similar like pg.Error:
type Error struct {
Severity string
Code ErrorCode
Message string
Detail string
Hint string
Position string
InternalPosition string
InternalQuery string
Where string
Schema string
Table string
Column string
DataTypeName string
Constraint string
File string
Line string
Routine string
}

我在软件包存储库上提出了同样的问题，这是我从存储库维护者那里得到的答案。
Ent包装或返回底层驱动程序的错误。因此，您可以使用类型断言或errors.Is/errors.As助手来提取这些类型。
请参阅我们集成测试中的示例：
https://github.com/ent/ent/blob/60e0328/entc/integration/integration_test.go#L1845-L1858

So I asked this same question on package repo and this is the answer I got from repo Maintainer.
Ent wraps or returns the underlying driver errors. So, you can either use type-assertion or errors.Is/errors.As helpers to extract these types.
See examples in our integration-test:
