Here's how to install PostgreSQL and have it run automatically at startup, on an Ubuntu 10.04 virtual machine using Vagrant. This took me a while to figure out:

Add the default lucid32 base box to your vagrant, if you haven't already:

host> vagrant box add lucid32 http://files.vagrantup.com/lucid32.box 

Now make a new lucid32 virtual machine and install postgresql on it:

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
