here's a patch for a utility function to look up the cast function for a from/to pair of types, as recently suggested by Alvaro. Although it only contains one use (in json.c), the upcoming jsonb generators would also use it twice. I'd like to get this committed fairly quickly so I can prepare an updated patch for the jsonb generators.
