I installed and created a Postgresql database on ubuntu. I then created the database using the following command:

sudo su postgres createdb mydatabase

However, I can't figure out where the database was initialized. I would like to be able to edit the hba.conf file and postgresl.conf files.

When I view the database using pgadmin I see the following information:

CREATE DATABASE mydatabase

  WITH OWNER = postgres

       ENCODING = 'UTF8'

       TABLESPACE = pg_default

       LC_COLLATE = 'en_US.UTF-8'

       LC_CTYPE = 'en_US.UTF-8'

       CONNECTION LIMIT = -1;

Any thoughts on how I can find the database cluster location?
