Reference and arrays

hi,
im using postgresql 8.0.1 and i want to be able to do the following:

create table t1 (name varchar(10), age int2);

create table t2 (position varchar(20), worker t1[]);

meaning i want to be able to declare worker as an array of t1. if that is possible how do i insert into values t2.
after that can i make a reference to another table using the array. something like this:

create table t3 (month varchar(20), bday reference t1[]);

or something as close to this as possible.

thanx a lot!
