Ola Paulo,

You need to take a look at the PostgreSQL documentation as well. Just
reading your college databases book won't cut it most of the time.

PostgreSQL has excellent documentation, especially the reference manual.
Take a look at it. So far both of your questions could have been answered
by taking a quick glance at the docs.
