PostgreSQL
The world's most advanced open-source database — and the industry default.
What is PostgreSQL?
PostgreSQL is a battle-tested relational database with an extension ecosystem that stretches it far beyond SQL: JSONB documents, full-text search, PostGIS for geospatial, pgvector for embeddings. Nearly every modern backend platform (Supabase, Neon, RDS) is Postgres underneath.
Our review
5.0The boring choice that is almost never wrong. Rock-solid reliability, serious SQL features, and an extension ecosystem (pgvector, PostGIS, TimescaleDB) that keeps it competitive in every new wave — including AI. Choose something else only when you have a specific, measured reason.
Pros
- + Extremely reliable and standards-compliant
- + Extensions cover search, geo, time-series, vectors
- + Universal hosting support, zero license cost
Cons
- − Connection model needs pooling at scale
- − Horizontal scaling requires external tooling
