there is no default password. on most unix and linux distributions, the
default authentication mode is set to 'ident' which means a given unix
user X can only connect as the postgres user X. initially, the only
postgres user is 'postgres', so...

(assuming you're on the typical unix/linux system, you didn't say)

$ sudo -u postgres psql

postgres=> alter user postgres password 'apassword';
postgres=> create user yerusername createdb createuser password
postgres=> create database yerusername owner yerusername;
postgres=> \q

$ ...

now as your regular user 'yerusername' you can connect to postgres, and
have the privileges to create new users and databases.

That sequence also modified the postgres user's password in case you
change the default authentication method to md5 (this is set in
pg_hba.conf, see the documentation for more details)
