- Course Overview
- This curriculum provides an intensive, modern look at the responsibilities and technical challenges faced by a professional PostgreSQL Database Administrator in a 2026 high-availability environment.
- Participants will explore the fundamental architecture of the PostgreSQL object-relational engine, gaining a deep understanding of how it processes transactions and manages concurrent user access.
- The course focuses on the evolution of PostgreSQL into a cloud-native powerhouse, highlighting the specific features and updates released in the January 2026 version.
- Instruction transitions from basic installation and configuration on local servers to advanced management of distributed database clusters across multiple geographic regions.
- A significant portion of the course is dedicated to the “Day 2” operations of a DBA, including routine maintenance, proactive health monitoring, and long-term capacity planning.
- Students will examine the internal storage mechanisms of the database, learning how the engine handles data on disk and how memory buffers impact overall system responsiveness.
- The course emphasizes a hands-on approach, utilizing realistic scenarios that mimic production outages, security breaches, and performance degradation to build practical resilience.
- Requirements / Prerequisites
- A solid foundational knowledge of the Structured Query Language (SQL) is required, including the ability to write complex JOINs, subqueries, and basic data manipulation commands.
- Familiarity with the Linux command-line interface (CLI) is essential, as the majority of the administrative tasks will be performed via terminal sessions and bash scripting.
- Students should have a basic understanding of computer networking concepts, such as IP addressing, ports, firewalls, and the client-server architecture model.
- Access to a computer (Windows, macOS, or Linux) with at least 8GB of RAM and administrative privileges to install the PostgreSQL binaries and virtualization software.
- Prior experience with any other relational database management system (such as MySQL, SQL Server, or Oracle) is beneficial but not strictly required for success.
- A willingness to engage in technical troubleshooting and a methodical mindset for diagnosing systemic issues within a complex software stack.
- Skills Covered / Tools Used
- Expert-level proficiency in psql, the primary command-line utility, for executing administrative commands and managing internal database objects.
- Detailed management of postgresql.conf parameters, specifically focusing on shared_buffers, work_mem, and maintenance_work_mem for granular performance tuning.
- Implementation of Host-Based Authentication (HBA) through the pg_hba.conf file to secure the database against unauthorized external connections.
- Utilization of pg_dump and pg_dumpall for logical data exports and the pg_restore utility for sophisticated data recovery strategies.
- Advanced usage of pg_basebackup to create physical copies of the database cluster, forming the foundation for streaming replication and standby servers.
- Mastery of VACUUM and AUTO-VACUUM management to prevent table bloat and ensure that storage space is reclaimed efficiently without impacting performance.
- Harnessing EXPLAIN and EXPLAIN ANALYZE to deconstruct query plans and identify inefficient sequential scans or suboptimal join methods.
- Monitoring and diagnostics using the pg_stat_activity and pg_stat_statements extensions to track real-time resource consumption and identify bottleneck queries.
- Configuration of Write-Ahead Logging (WAL) and Point-In-Time Recovery (PITR) to ensure data durability and the ability to restore to specific timestamps.
- Benefits / Outcomes
- Graduates will possess the technical competence to manage mission-critical PostgreSQL instances with zero data loss and maximum uptime for enterprise applications.
- The ability to design and implement a comprehensive security framework that includes encryption at rest, encryption in transit, and robust audit logging.
- Significantly improved career prospects in the fields of Database Administration, DevOps Engineering, and Data Reliability Engineering across the global tech market.
- Confidence in migrating legacy database systems to PostgreSQL while maintaining data integrity and optimizing for the target environment’s specific strengths.
- The expertise required to automate repetitive administrative tasks, such as index rebuilding and log rotation, using cron jobs and custom administrative scripts.
- A deep understanding of high-availability architectures, allowing the student to set up failover mechanisms that protect the business from hardware failures.
- The skills needed to serve as a consultant for application developers, providing guidance on schema design and query optimization for better scalability.
- PROS
- Accelerated 3.5-hour format eliminates unnecessary filler, focusing exclusively on high-impact administrative skills that are immediately applicable in the workplace.
- Includes the very latest 2026 software updates, ensuring that students are learning modern best practices rather than outdated legacy techniques.
- Strong emphasis on practical, real-world troubleshooting scenarios that build the confidence needed to manage production-grade database environments.
- Balances the use of graphical interfaces like pgAdmin with powerful command-line tools to provide a well-rounded technical toolkit.
- CONS
- The fast-paced nature of the 3.5-hour duration requires students to have a very strong prior grasp of SQL, as there is no time spent on basic query syntax.
