PostgreSQL configuration without password on Ubuntu for Rails

Abstract

You could have postgre installed on localhost with password (or without user or password seted after instalation) but if we are developing we really don't need password, so configuring postgre server without password for all your rails project is usefull.

Install Postgre packages

  • postgresql
  • postgresql-client
  • libpq-dev
