About the Course
Effective PostgreSQL database administration demands more than knowing SQL syntax or following a tutorial to set up a server. Organizations need DBAs who can show five things clearly: the current health posture of every database instance, where performance bottlenecks and security risks concentrate, realistic capacity and growth projections, the highest-impact tuning and architecture decisions for current workloads, and verifiable evidence that backup, recovery, and failover mechanisms actually work when invoked. This course takes you through each of these dimensions systematically, grounding every concept in the operational reality of production PostgreSQL environments serving transactional applications, analytics platforms, and mixed workloads.
The training converts scattered PostgreSQL knowledge into a structured administration system. You will develop capabilities in server installation and configuration management, memory and storage parameter tuning, authentication and role-based access control, logical and physical backup strategies, point-in-time recovery execution, streaming replication and high availability architecture, query performance analysis using EXPLAIN and pg_stat views, vacuum and autovacuum optimization, connection pooling, and proactive monitoring with alerting. Every module emphasizes hands-on practice using realistic scenarios drawn from production environments, so you leave with tested playbooks rather than theoretical notes.
This course acknowledges the real constraints DBAs face: limited maintenance windows, legacy application dependencies, budget restrictions on hardware and tooling, pressure to maintain uptime while implementing changes, and the challenge of managing PostgreSQL alongside other database platforms. The methodology is designed for professionals who must deliver measurable improvements in database reliability and performance within these constraints, using PostgreSQL's native capabilities and open-source ecosystem tools rather than assuming access to expensive commercial add-ons.

Course Objectives
This course equips you to plan, deploy, and optimize PostgreSQL database environments, execute robust backup, recovery, and replication strategies, and measure and report on database performance, security, and availability to meet organizational and compliance requirements.
By the end of this course, you'll be able to:
- Understand the PostgreSQL architecture, including process model, memory structures, storage layout, and write-ahead logging (WAL), to make informed administration decisions rooted in how the engine actually operates
- Measure database health and performance using pg_stat views, system catalogs, EXPLAIN ANALYZE output, and log analysis to quantify bottlenecks with data rather than guesswork
- Design and implement a server configuration strategy by tuning shared_buffers, work_mem, effective_cache_size, WAL parameters, and autovacuum settings based on workload profiling and hardware capacity
- Apply robust security controls including pg_hba.conf authentication rules, role-based access hierarchies, row-level security policies, SSL/TLS encryption, and audit logging to harden PostgreSQL against unauthorized access
- Develop and execute comprehensive backup and recovery plans using pg_dump, pg_basebackup, continuous WAL archiving, and point-in-time recovery (PITR) with documented and tested recovery runbooks
- Assess and implement replication architectures including streaming replication, logical replication, and failover mechanisms to meet high availability and disaster recovery objectives
- Set performance baselines and track improvement through query optimization, index strategy, partitioning, connection pooling with PgBouncer, and vacuum/bloat management tied to measurable KPIs
- Communicate database health, capacity forecasts, risk exposure, and improvement recommendations to technical teams and organizational leadership using dashboards, reports, and structured review cadences
Requirements & Prerequisites
To gain maximum value from this course, you should have:
- Working knowledge of SQL (SELECT, INSERT, UPDATE, DELETE, JOINs, subqueries) and experience querying relational databases
- Basic familiarity with Linux/Unix command line operations (file navigation, process management, text editing, package installation)
- Foundational understanding of relational database concepts (tables, indexes, schemas, transactions, normalization)
- Access to a computer with the ability to install PostgreSQL or connect to a lab environment (setup instructions will be provided before the course begins)
- Prior exposure to any database administration tasks (backups, user management, basic troubleshooting) is helpful but not mandatory
