optimization join on random value

Hello guru of postgres,  it's possoble to tune query with join on random 
string ?
i know that it is not real life example, but i need it for tests.

soe=# explain
soe-#  SELECT   ADDRESS_ID,
soe-#           CUSTOMER_ID,
soe-#           DATE_CREATED,
soe-#           HOUSE_NO_OR_NAME,
soe-#           STREET_NAME,
soe-#           TOWN,
soe-#           COUNTY,
soe-#           COUNTRY,
soe-#           POST_CODE,
soe-#           ZIP_CODE
soe-#         FROM ADDRESSES
soe-#         WHERE customer_id = trunc( random()*45000) ;
                                         QUERY PLAN
-------------------------------------------------------------------------------------------
  Seq Scan on addresses  (cost=0.00..165714.00 rows=22500 width=84)
    Filter: ((customer_id)::double precision = trunc((random() * 
45000::double precision)))
(2 rows)

soe=# \d addresses;
soe=# \d addresses;
                   Table "public.addresses"

Foreign-key constraints:
     "add_cust_fk" FOREIGN KEY (customer_id) REFERENCES 
customers(customer_id) DEFERRABLE



same query in oracle same query use index access path:
