'password authentication failed for user "postgres"'

I have installed PostgreSQL 8.4, Postgres client and Pgadmin 3. Authentication failed for user "postgres" for both console client and Pgadmin. I have typed user as "postgres" and password "postgres", because it worked before. But now authentication is failed. I did it before a couple of times without this problem. What should I do? And what happens?

psql -U postgres -h localhost -W
Password for user postgres: 
psql: FATAL:  password authentication failed for user "postgres"
FATAL:  password authentication failed for user "postgres"
postgresql

The response of staff is correct, but if you want to further automate can do:

$ sudo -u postgres psql -c "ALTER USER postgres PASSWORD 'postgres';"

Done! You saved User = postgres and password = postgres.

If you do not have a password for the User postgres ubuntu do:

$ sudo passwd postgres
