I think you'd need to double-quote each polygon within the array
literal.

        '{"((432,89), (45,87), (89,87))", "..."}'

The array parser doesn't think parens are special, so it's not going to
magically distinguish array commas from polygon commas for you.

BTW, if you are using 7.4, the ARRAY[] constructor syntax might be
easier to use.

                        regards, tom lane
