It typically does them by converting the source value to text and then converting that string to the target type. If we were designing that language today, I doubt we'd have accepted such a definition, but changing it now would break a lot of code ... regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
