The FuncExpr cases in astvisit files were manually constructing function output but not including the OVER clause, causing argument-less window functions like ROW_NUMBER() and RANK() to fail with "misuse of window function" errors.
…ause The inferColNameFromExpr function was manually constructing the decorated column for functions with 0 or 2+ arguments using fmt.Sprintf, which did not include the OVER clause for window functions like ROW_NUMBER(), RANK(), etc. Changed to use astformat.String(expr, formatter) which properly calls FuncExpr.Format() and includes the OVER clause.
The previous change broke json_extract and other multi-argument functions because astformat.String doesn't apply the same recursive processing to arguments that the manual construction does. Now only use astformat.String when expr.Over != nil (actual window functions), keeping the original fmt.Sprintf behavior for regular functions to maintain proper argument decoration.
