You can also go into the pg_hba.conf file, and at the bottom put a #
sign in front of host and then instead of the method set to 'md5', put
'trust'. This will allow you to login without a password, and then you
can reset it.

Two ways to do this.
1: log in in single user mode. To do so, shut down the db, then use
the postgres command to bring up the db in single user mode, like so:
postgres -D /my/data/dir --single
and then issue the command to change the password.
OR
2: change pg_hba.conf to trust on some known IP, hup the server
(pg_ctl -D /my/data/dir reload) and then log in as postgres and change
your password.
