Why PostgreSQL Is Eating the Database World

PostgreSQL has become the default database choice for new projects, overtaking MySQL and MongoDB. Why: open source, ACID compliant, JSON support (competing with document databases), PostGIS (geospatial, no rival), extensions ecosystem (pgvector for AI/ML), and improving performance (parallel query, partitioning). Major adopters: Instagram (moved from Django ORM to raw Postgres), Tesla, Uber, Spotify. Cloud offerings: AWS RDS, Google Cloud SQL, Supabase, Neon (serverless), and CockroachDB (distributed). The database consolidation trend: Postgres handles relational, document, vector, and time-series workloads, reducing the need for specialized databases.
