PostgreSQL Is Enough
The article argues that PostgreSQL is a versatile and powerful database sufficient for most application needs, often eliminating the need for separate specialized data stores like Redis, MongoDB, or Elasticsearch. It highlights PostgreSQL's support for JSON, full-text search, indexing, and advanced features, suggesting developers should master it before adding other technologies to their stack.
Background
A growing movement in the software industry pushes back against adding separate tools for every job—e.g., Redis for caching, Kafka for messaging, Elasticsearch for search—when a single PostgreSQL database already handles those tasks adequately for most products. The "PostgreSQL Is Enough" manifesto argues that for the vast majority of applications (especially startups and mid-size projects), Postgres's built-in features (JSON, full-text search, indexing, pub/sub, extensions like PostGIS, etc.) eliminate the complexity and operational cost of running a dozen specialized databases. This reflects a broader "boring technology" philosophy: choose mature, well-understood tools over trendy ones to keep teams small, deployments simple, and maintenance low.
