I am a PostgreSQL newbie.
How is this table useful for me?
I want to develop a database application.
I want to store personal data like name and birth date!

Actually, I feel confused.  What should I do with this table?
Is it part of the database system?  Will the database be broken if
I drop it?  Do I have to ship it with my application?

No, I'm not the kind of person who reads a manual to figure out what to
do with this table.  I want to start coding *right now*.

I have found a sample application for personal data on the internet.
How can I make it work with this table?

Good that you mention that!  I have wondered what to do with it.
When I first connected to PostgreSQL, I created a sample table, but the
senior developer from the other office told me that this is the "postgres"
database and that I shouldn't create any objects there.

What is it good for?  Can I delete it?

Yours,
