> If IsBuildInFunction returns false, then find_udf should return true
>     directly, which means that the statement contains UDF. Otherwise, it
>     should continue to recursively determine the args of FuncExpr through
>     expression_tree_walker, because FuncExpr may contain recursive calls.
>     For example, suppose "A" is an UDF, then "select A::text" meets this
>     situation. The outter FuncExpr is "text" and the inner FuncExpr is "A".
