Maps rows to lists by applying PROC to every row and using its result in the result list on the position corresponding to that of the row. This procedure is not guaranteed to walk the result set in any particular order, so do not rely on the order PROC will be called.

(import postgresql)

(let ((conn (connect '((dbname . test)))))
   (row-map* + (query conn "SELECT 1, 100 UNION SELECT 2, 200")))
 => (101 202)
