A solo developer and tech co-founder shares their experience using Postgres as the single infrastructure component for an early-stage startup, replacing Elasticsearch, Redis, RabbitMQ, and other services. By leveraging Postgres features like full-text search, trigram matching, SELECT FOR UPDATE SKIP LOCKED for job queues, JSONB columns for caching and key-value storage, and materialized views, they eliminated operational overhead and moved faster. The core argument: at early stage, simplicity and iteration speed matter more than using the optimal tool for each job. The approach has limits at scale, but you'll know when to migrate individual components rather than untangling a complex multi-service mess.
