Postgres Is Eating the Database World

The extensible monolith

Every few years, a new database category emerges — and a few years later, Postgres absorbs it. Vector databases were the latest example: purpose-built vendors raised hundreds of millions, then pgvector shipped and captured the majority of production workloads almost overnight.

Why extensions win

The pattern is structural. A specialized database must rebuild everything Postgres already has: transactions, replication, backups, access control, an ecosystem of tools. An extension inherits all of it for free. For most workloads, 80% of the specialized performance with 100% of the operational maturity is the winning trade.
