What it is
PostgreSQL is a powerful, standards-compliant open-source RDBMS with rich SQL, JSON, extensions (PostGIS, pgvector), and strong reliability.
The default open-source relational database — flexible, reliable, and extensible.
When it fits — and when it doesn’t
A good fit for
Most application databases
Reliable, flexible relational store with JSON support
RAG/AI apps via pgvector
Vector search alongside relational data
Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Self-managing at scale is non-trivial
Tuning, replication, and HA take expertise (mitigated by managed hosts)
- 02
Defaults need tuning for big workloads
Out-of-box config is conservative
What it does well
Extremely capable and extensible
Rich SQL, JSONB, full-text, and extensions like PostGIS/pgvector
Rock-solid reliability
Decades of production hardening; strong ACID guarantees
Ubiquitous managed options
Neon, Supabase, RDS, and more offer hosted Postgres
