PostGreSQL installation

Wiki to install relational database PostGreSQL on different platforms.

Mac

• Getting Homebrew: /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
• Installing PostgreSQL: brew install postgresql
• Let’s go ahead and start Postgres running, and make sure Postgres starts every time your computer starts up. Execute the following command: pg_ctl -D /usr/local/var/postgres start && brew services start postgresql
• Finally, let’s make sure Postgres is installed and running. Let’s check what version is running: postgres -V

Ubuntu

• $ sudo apt-get update
• $ sudo apt-get install postgresql postgresql-contrib
• $ sudo -i -u postgres
• $ psql

Configuring Postgres for the project

• Login to the PostgreSQL console, if you have not created the DB, type CREATE DATABASE sih17;, this will create the database required for the project.
• Now the since the DB has been created now, we need to associate a user to the db, we can do this by typing CREATE USER sih17_admin WITH PASSWORD 'sih17winners'; in the PostgreSQL console.
• Give full access to the db by:
• ALTER ROLE sih17_admin SET client_encoding TO 'utf8';
• ALTER ROLE sih17_admin SET default_transaction_isolation TO 'read committed';
• ALTER ROLE sih17_admin SET timezone TO 'UTC';
• GRANT ALL PRIVILEGES ON DATABASE sih17 TO sih17_admin;
• These steps should be good enough to set up the project.
