Where can I find Postgresql training files

Question

I installed postgresql on my ubuntu computer using

apt-get install postgresql-9.1

Now I am reading the manual , but could not understand where the textbook files are located (for example, basics.sql).

Where can I find or download them?

Answer 1

They are in the original PostgreSQL distribution:

https://github.com/postgres/postgres/tree/master/src/tutorial

Also, the latest PostgreSQL is 9.3, not 9.1:
