Stop Chasing ‘Best of Breed’ Databases. Use Postgres for Everything.
The industry sold us on polyglot persistence—the idea of using the ‘best tool for the job’ for every workload. In reality, it’s an operational nightmare. By standardizing on PostgreSQL for everything from relational data to JSON documents and vector search, you trade marginal performance gains for massive cognitive and operational simplification. Stop chasing shiny tools and reclaim your engineering velocity.
