Course Overview

The PostgreSQL Database Fundamentals with Performance & Tuning course by Oracle is designed for database administrators, DevOps engineers, and cloud architects seeking to master PostgreSQL in enterprise environments. While Oracle is best known for its proprietary database, this specialized training bridges open-source expertise with Oracle-grade performance methodologies. It aligns with the EDB Postgres AI Database Essentials Certification Exam (exam code CPSDBA), preparing professionals for roles such as PostgreSQL DBA, Database Engineer, and Cloud Database Specialist. With PostgreSQL powering over 40% of public cloud database workloads according to Stack Overflow’s 2023 survey, demand for certified talent continues to grow across fintech, SaaS, and government sectors.

Participants engage with core tools and technologies including PostgreSQL 15+, pg_stat_statements, auto_explain, BRIN and B-tree indexes, WAL (Write-Ahead Logging), and the pg_buffercache extension, all within Oracle’s dedicated OU SGD lab environment. The hands-on labs emphasize real-world application, requiring students to configure high-availability clusters, optimize slow queries using EXPLAIN ANALYZE, implement autovacuum tuning, and build monitoring dashboards using pg_stat views. A capstone project involves diagnosing and resolving a simulated production-level performance bottleneck, reinforcing skills in query planning, index optimization, and memory configuration within a secure, sandboxed training infrastructure.

This course prepares candidates for the EDB Postgres AI Database Essentials Certification, a credential recognized by major employers including AWS, Google Cloud, and EnterpriseDB for its rigorous validation of PostgreSQL expertise. Certified professionals report an average salary increase of 20%, with PostgreSQL DBAs in the U.S. earning between $105,000 and $135,000 annually according to 2024 industry data. Koenig Solutions enhances this learning path with Guaranteed-to-Run scheduling and official Oracle-aligned courseware, ensuring consistent access to up-to-date content. Graduates are positioned to advance into senior database roles, cloud migration projects, or performance engineering positions in organizations leveraging PostgreSQL at scale.
