PostgreSQL is the most-named open-source database in job postings — resumes rank on operational and design depth: schema modeling, indexing, query plans, and scale markers, with the exact spelling 'PostgreSQL' matching more JD filters than 'Postgres'.
It appears in 10% of 2,367 engineering postings in our 15 August 2026 snapshot . Densest in Software Engineer (15%) .
Job descriptions rarely ask for PostgreSQL alone — these co-terms appear in the same postings and are screened together. Cover the ones you've genuinely used.
Public ATS boards (Arbeitnow, Greenhouse, Ashby, Google Careers, Lever, RemoteOK, Remotive). Not LinkedIn or Indeed. Percentages are share of postings that already mention PostgreSQL.
A skill in a list is a claim; a skill in a bullet with an outcome is evidence. Patterns to adapt with your real numbers:
“Designed the PostgreSQL schema (partitioned event tables, JSONB payloads) sustaining 10k writes/sec for an analytics product”
“Diagnosed and fixed the top slow queries via EXPLAIN analysis and covering indexes, cutting p95 API latency 60%”
Put "PostgreSQL" in your skills section in its exact form, then prove it in at least one experience bullet with context and an outcome — a skill that appears only in a list reads as padding to recruiters. PostgreSQL is the most-named open-source database in job postings — resumes rank on operational and design depth: schema modeling, indexing, query plans, and scale markers, with the exact spelling 'PostgreSQL' matching more JD filters than 'Postgres'.
Job descriptions that ask for PostgreSQL typically also screen for: Python, Kubernetes, AWS, TypeScript, Java. Include the ones you've genuinely used — co-keyword coverage is how ATS ranking separates real practitioners from list-padders.
List it only if you could answer interview questions about it comfortably. A safer honest framing for light experience is grouping it under a "familiar with" tier, separate from your core skills — inflated skill claims surface fast in technical interviews.
Paste a job description that requires it — RoleTuner shows whether your resume surfaces PostgreSQL and its co-keywords the way an ATS reads them, free.
