"PostgreSQL is a powerful, open source object-relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness."

The recommended platform is Debian 7 using the postgresql-9.1 package

apt-get install postgresql-9.1 postgresql-server-dev-9.1
su - postgres
createdb production

After installation, a user named postgres is created with superuser access to the database cluster. The remainder of the database configuration is part of the Ruby on Rails and Kamailio installations.
