// Overview

How we use PostgreSQL

PostgreSQL is our default database for all applications with relational data — which is most of them. Its ACID guarantees, rich query language, JSON support, full-text search, and pgvector extension for AI workloads make it an exceptionally capable system.

// Use cases

  • Transactional SaaS applications
  • Multi-tenant data stores
  • Financial data with ACID requirements
  • AI applications with vector similarity search
  • Complex reporting with window functions

// Why it matters

ACID transactions

Full transaction support with serialisable isolation — appropriate for any application where data integrity is non-negotiable.

JSON + relational

jsonb columns enable flexible schema sections within a structured relational model — no need to choose between relational and document stores.

pgvector for AI

Native vector similarity search via pgvector makes PostgreSQL the right choice for RAG applications without introducing a separate vector database.
