Correct update statement

Please help, we are using postgreSQL 9.2.4. I need to update over 9000 rows. See the query below: A table called contact has got addr_id field as null which is incorrect. So now I need to update contact table for each account (cus_acno is in cus table) where contact_addr_id is null. For example using the first of the results below: I need take set addr_id (in contact table) to 187479 where cus_acno = 243492 and con_id = 119360

Example:

select distinct(cus_acno), contact.con_id, address.addr_id from address join person using (addr_id) join cus using (per_id) join link_contact using (cus_acno) join contact using (con_id) where contact.addr_id is null;
cus_acno | con_id | addr_id
----------+--------+---------
   243492 | 119360 | 187479
   393701 | 119824 | 458532
   388538 | 118413 | 453178

Thanks
