  - To create local postgres db (first run only):
    - Linux:
      initdb db; sudo chown -R $USER:users /run/postgresql; postgres -D db;
    - Mac:
      initdb db; sudo chown -R $USER:staff /var/run/postgresql; postgres -D db;
    - Windows:
      initdb db
      postgres -D db

  - Then in another Terminal window: 
    - Unix:
      createdb closet; psql closet < server/schema.sql
    - Windows:
      createdb -U postgres closet
      psql -U postgres closet < server/schema.sql

  - For Windows, change the postgres password to 'password'
