I'm building a website that's open to anyone for viewing and that only authorised users can modify, using the following pseudocode for handling logins.

Have I left any obvious holes? 

login
    - read username & password, check against database
      - if they're correct
        - create pseudo-random session ID
        - store session ID on database
        - return session ID in cookie
        - cookie lasts 1 hour
        - session ID on database lasts 1 hour (script for removal?)
    - else user is not logged in, gets view privs only

checking login - to be done before any admin action
    - read session from cookie
    - if session exists on database, user is logged in, gets admin
      privs
    - else user is not logged in, gets view privs only
      - try to delete cookie

logout
    - delete database session
    - try to delete cookie
