database/sql:how to avoid question mark as placeholder using postgres ?

[rw202307]

What do you want to ask?

I want to take question mark(?) as operator in dealing jsonb in postgresql.(Question mark(?) can tell if the text string exist as a top-level key or array element within the JSON value.)
However, while running program, one error occurs which says that, goframe2.7.2 take the question mark(?) as placeholder in my query. And this is my query: select col ? 'k1' from table1. ("col" is tables1's field with type jsonb in postgresql)
My question is the title shown above. How to fix it??
