PostgreSQL-CE certifications generally reflect community-driven validation of practical skills related to the PostgreSQL database ecosystem rather than proprietary vendor credentials. At a high level, they tend to cover core relational database concepts, PostgreSQL architecture, installation and configuration, SQL usage, data modeling, indexing, performance tuning, backup and recovery, security fundamentals, and routine administration and troubleshooting. Exams typically expect familiarity with real-world operational scenarios, an understanding of open-source best practices, and the ability to work across common operating environments. Candidates are usually expected to have hands-on experience, comfort with documentation, and a solid grasp of how PostgreSQL-CE behaves in production contexts. These certifications commonly support career paths such as database administrator, data engineer, backend developer, system administrator, or DevOps professional working with PostgreSQL-based systems.
