Question
How can I accesss the Postgres database server on the RaQ3 to add databases,
create tables, and add users?


Response
NOTE: UNSUPPORTED. Cobalt Networks currently does not offer support for
third party software or modified systems. Please contact the appropriate
software vendor for further assistance. Modifications through root shell
access could potentially void your warranty. A fee will be assessed by
Cobalt for fixes or rebuilds on systems with unsupported modifications.

The following process will give the postgres user called "admin" the
super-user privilage. Once this is done, a user can log into postgres using
the admin account and modify itself to allow creation of users and
databases.

1. telnet in as admin

2. use su - to switch to root

[admin@raq3 admin]$ su -
Password:

[root@raq3 /root]#

3. use an editor and open the file /home/pgsql/pg_hba.conf

[root@raq3 /root]# vi /home/pgsql/pg_hba.conf

4. Change local all crypt to local all trust

5. use su to switch to the user ID postgres

[root@raq3 /root]# su postgres
[postgres@raq3 /root]$


6. Now run the psql program to connect to the database server.

[postgres@raq3 /root]$ psql cobalt

type g or terminate with semicolon to execute query
You are currently connected to the database: cobalt

cobalt=>

7. Enter the following commands to give super-user privilage to admin and
quit.

cobalt=> update pg_shadow set usesuper='t' where usename='admin';
UPDATE 1
cobalt=> q
[postgres@raq3 /root]$

8. Use the exit command to become "root" again.

9. Now open the /home/pgsql/pg_hba.conf file and change "local all trust"
back to "local all crypt".

It is now possible to access postgres using the postgres account "admin".
The password for this account is stored in the file /etc/cobalt/.meta.id and
should not be changed. If the password needs to be changed, it must be
changed in the pg_shadow table and the /etc/cobalt/.meta.id file. Be sure to
maintain file permissions on the file or system security could be
compromised.
