Regarding Postgres Plus Associate Certification

Hi to everybody, i just wanna ask you if somebody that already has the
certification or if is studying to get it knows if there's a book (or a set
of books) that you recommend me that contains most of the necessary
information to cover the topics of the certification, that are the next:

- PostgreSQL System Architecture
- Installation
- Configuration
- Creating and Managing Databases
- Introduction to PSQL
- pgAdmin III
- Security basics
- SQL
- Backup and Recovery
- Point-in Time Recovery
- Routine Maintenance
- Postgres Data Dictionary
- Moving Data

Or if the documentation is enough to cover those topics, because i want to
study to get the certification.

Regards.
