Well, you're right, here is my workaround:
-- purpose: workaround the dumb value to bigint conversion of postgresql
-- usage getmebigint(int);
drop FUNCTION getmebigint(int);
CREATE FUNCTION getmebigint(int) RETURNS bigint AS
        id bigint;
        select $1 into id;
        RETURN id;
   language 'plpgsql';

And in table definitions you use getmebigint(0) that makes the
transformation between value type and bigint type

        name_id      bigint not null default getmebigint(0),

Awful but is working until you'll find the problem.

Question: there isn't any cast operator like this?:
        name_id      bigint not null default bigint(0)

Anyway, thankz for the fast reply.
