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) ;
