PostgreSQL Database Administration Fundamentals
Manage, optimize, and troubleshoot PostgreSQL databases in production.
About This Assessment
PostgreSQL DBA roles have 400+ open positions on Indeed alone with consistent hiring across healthcare, finance, and tech sectors. Entry-to-mid level candidates frequently exaggerate database experience, making hands-on verification critical. This assessment tests practical PostgreSQL administration including performance tuning, backup/recovery, and user management.
What Candidates Will Do
Diagnose and fix slow-running queries using EXPLAIN ANALYZE and create appropriate indexes
Configure PostgreSQL backup strategy with pg_dump and test restoration to a new database
Manage database users, roles, and permissions following least-privilege principles
Troubleshoot connection issues and optimize postgresql.conf for a specific workload
Automated Grading
Verify queries execute within performance thresholds after optimization, backup files are valid and restorable, user permissions correctly restrict access, and configuration changes improve specified metrics (connection pooling, memory allocation).
Environment
Ubuntu VM with PostgreSQL 15+ installed, sample database with 100K+ rows pre-loaded, intentionally slow queries, and misconfigured settings. pgAdmin or psql CLI available.
