EDB PostgreSQL Professional

No. This is an independent study guide. It is not affiliated with or endorsed by EDB, and it contains no official questions. Always verify exam logistics, registration, and pricing through EDB's own channels, since the certification page was unreachable when this page was last checked on 2026-11-07.

Unknown. The official certification page returned a 404 on 2026-11-07, so question count, time limit, and delivery format could not be confirmed. Do not plan around numbers quoted elsewhere. Treat any specific figure you see as unverified until EDB publishes it, and budget extra time for hands-on tasks.

Neither is confirmed here. Passing score and fee are recorded as unknown pending an official source. Candidates should ask EDB directly before scheduling, and should not assume a score scale or currency. Prepare to a high standard regardless, since performance-based PostgreSQL exams typically reward demonstrated accuracy over partial credit guessing.

Expect professional-level difficulty: questions assume you can read query plans, reason about WAL and replication lag, and recover a cluster under pressure. Comfort with daily production administration is the realistic baseline. If you have never configured streaming replication or performed point-in-time recovery, build that experience before attempting the exam.

Start with core administration: roles, privileges, configuration, storage, and maintenance. Then performance tuning, because plan reading depends on that foundation. Next high availability, replication, and backup/recovery, which combine administration and tuning knowledge. Finish with migration, security, and platform operations, where you apply everything under real constraints.

Candidates often memorize syntax but cannot interpret EXPLAIN output, misjudge autovacuum and bloat behavior, confuse physical and logical replication limits, or assume a base backup alone provides point-in-time recovery. Others neglect role and privilege inheritance details, or miss that restoring WAL requires correct archive and recovery target configuration.

Unverified. Retake policy and validity period are not published in the source material available here, so they are marked for review. Check with EDB before registering so you understand waiting periods and renewal obligations. Plan your study so a first attempt is realistic rather than relying on an assumed retake window.

Run a local cluster and practise: create roles with inheritance and row-level security, corrupt and recover a database using base backup plus archived WAL, set up streaming replication and measure lag, then tune slow queries with EXPLAIN (ANALYZE, BUFFERS), indexes, and statistics. Finish with a small schema migration including data validation and rollback planning.

No. The four domains are shown at 25 percent each as a provisional, evenly split study scaffold because no official blueprint could be retrieved. Actual weighting may differ. Use the domains to organize learning, not to predict question distribution, and recheck EDB's published objectives before your exam date.
