RECIPE
Install PostgreSQL
Install the server
Initialize the database
The system should return "Initializing database [ok]."
Check the configuration and start the service
service postgresql start
PostgreSQL creates a user called "postgres" which accesses the database functions. You'll need to switch to that user to make sure things are all up and running correctly.
You should now be logged in as the postgres user.
Connect to the database
You should now be at a PostgreSQL prompt which looks like this "postgres=#"
Success!
If you've gotten to the prompt above, PostgreSQL is up and running successfully. You can type \q to quit out of the PostgreSQL prompt
