如何在查询中使用问号？

Question

I use gorm and postgresql9.4.

The operator ?| is used in my query.

DB.Where(`a->'b' ?| ARRAY['1','2','3'] `)

print sql:

WHERE  a->'b' | ARRAY['1','2','3']

The operator ?| be converted |. This is not what I want.

Thanks.

That's a known issue. Intended or not, ??? will escape the question mark.
