Course Overview

The PostgreSQL Essentials course by PostgreSQL, delivered through EnterpriseDB (EDB), is designed for database administrators (DBAs), IT professionals, and aspiring data engineers seeking foundational expertise in one of the most widely adopted open-source relational databases. This comprehensive training prepares learners for the PostgreSQL Essentials certification exam and equips them with core competencies in installation, configuration, security, and maintenance of PostgreSQL databases. Target roles include Junior DBA, Database Administrator, and Systems Engineer, with PostgreSQL powering over 40% of open-source database deployments globally according to EDB’s 2023 survey, underscoring its demand across enterprises and cloud environments.

Participants engage with key tools and technologies including psql, pgAdmin4, PostgreSQL YUM Repository, pg_basebackup, logical replication, and Point-in-Time Recovery (PITR) within a hands-on lab environment running on Rocky Linux-based virtual machines. The labs guide students through real-world scenarios such as installing and configuring PostgreSQL clusters, securing database objects, performing physical and logical backups, and restoring data using PITR. A capstone project involves building a fully managed PostgreSQL instance from scratch, including user role setup, schema design, automated vacuuming, and high availability configuration via streaming replication—mirroring tasks performed by production DBAs in enterprise settings.

This course directly prepares candidates for the PostgreSQL Essentials certification, recognized across the industry as proof of foundational DBA proficiency and endorsed by EDB, the leading contributor to the PostgreSQL ecosystem. Certified professionals report an average salary increase, with entry-level PostgreSQL DBAs earning between $75,000 and $95,000 annually in the U.S., per 2024 labor market data. Koenig Solutions enhances this learning path with Guaranteed-to-Run batches, official EDB courseware, and optional 1-on-1 mentoring, ensuring personalized support. Upon completion, graduates are positioned to advance into mid-level database administration or cloud data engineering roles, leveraging PostgreSQL’s growing footprint in modern data architectures.
