About this product
PostgreSQL (13) DB Administration – Study Guide
This study guide is a comprehensive resource designed for learners preparing to administer PostgreSQL 13 databases. It covers foundational to advanced DBA concepts, including installation, configuration, architecture, security, performance tuning, backup/restore, high availability, and troubleshooting.
The guide explains PostgreSQL’s internal architecture, memory components, processes, and storage structures. It includes hands-on steps for creating databases, managing schemas, users, and roles, and configuring key parameters. Important administrative areas such as WAL files, checkpoints, autovacuum, monitoring queries, indexing strategies, and query optimization are also covered in detail.
Additionally, it provides practical instructions and examples for performing backups using pg_dump and pg_basebackup, restoring databases, setting up streaming replication, configuring hot standby environments, analyzing logs, and maintaining database health. This study guide acts as both an interview preparation document and a practical reference manual for real-time PostgreSQL administration.
