Review Comment:
@qingwei91 Thanks for the pointer, at the point in the code that you are
looking at we have access to the statement. But where I am in the code does
not. I see that the JdbcFilterPushdownPreparedStatementVisitor hard codes a '?'
literal as the placeholder for the parameter for simple expressions. Still
looking into this.
