Change the PostgreSQL password

You can modify the PostgreSQL password using the following command at the shell prompt:

$ psql -U postgres
postgres=# alter user postgres with password 'NEW_PASSWORD';
postgresl=# \q

Reset the PostgreSQL password

If you don’t remember your PostgreSQL database password, you can follow the steps below to reset it to a new value:

  • Change the authentication method in the configuration file at installdir/postgresql/data/pg_hba.conf from md5 to trust and reload the configuration.

    $ sudo sed -ibak 's/^\([^#]*\)md5/\1trust/g' installdir/postgresql/data/pg_hba.conf
$ sudo -u postgres pg_ctl reload

  • Connect to the PostgreSQL database and set the password to a new value:

    $ psql -U postgres
postgres=# alter user postgres with password 'NEW_PASSWORD';
postgresl=# \q

  • Finally, change the authentication method back to md5 and reload the old PostgreSQL configuration:

    $ sudo sed -i 's/^\([^#]*\)trust/\1md5/g' installdir/postgresql/data/pg_hba.conf
$ sudo -u postgres pg_ctl reload

You should now be able to connect to PostgreSQL with the new password.
