don't forget, you can create types via create table:
create table foo as
(
a int default 1,
...
check (a<5)
);
create table bar(f foo);
insert into bar default values; -- should foo defaults fire?? I say
probably, but check constraints should definately be enforced
(currently they are not).
(since you can alter the table later, there is very little reason not
to create types with create table always).
