Which book should I choose to quickly learn PostgreSQL?

Question

PostgreSQL

Good afternoon.
I have experience and knowledge of MySQL database, but for learning I want to transfer one of my projects to PostgreSQL.
Unfortunately, there is not much time to learn PostgreSQL, I would like to find a book that has basic administration, data types and query examples. If there is a comparison with MySQL - even better.
What to choose?

Answer 1

postgresql.leopard.in.ua/html
https://wiki.postgresql.org/wiki/Main_Page
https://www.postgresql.org/docs/

Answer 2

And there is something from the paper edition that you could buy (ozon.ru or other stores) and so that you don’t feel sorry for the money spent. The amount is not important.
