tasks automation, marketing campaigns, help desk, POS, etc. Technical
features include a distributed server, flexible workflows, an object
database, a dynamic GUI, customizable reports, and SOAP and XML-RPC

you have to do is issue the following command:
  createuser -U postgres --no-adduser terp

no need to set a password on localhost. However, if you are going to run
postgresql on a different server, you will have to run createuser like this:
  createuser -U postgres --no-adduser -P terp
