PostgreSQL for Everything

Contrary to popular belief, the answer to everything is not 42—it's PostgreSQL. This article argues that PostgreSQL is not just a rock-solid relational database but a versatile tool that can replace many specialized systems: full-text search (Solr/Elastic), document storage (MongoDB), message queues (Kafka/RabbitMQ), time-series databases (Clickhouse), vector databases for AI, caching (Redis), file systems, graph databases, and even microservices. With its stability, ease of use, and powerful extensions, PostgreSQL simplifies IT setups and handles a surprising range of workloads.
