Find attached v3 of the patch. changes include:
- fix deep recursion due to accidental reversal of check in encode_array_literal
- add proper support for stringifying composite/row types. I did not
find a good way to quote these from the perl on the fly, so instead we
compute it the same way we used to and store the string inside the new
object along with the array :(.
- misc whitespace and code touchups
