PlanetScale is launching Postgres support (currently in private preview), driven by customer demand after their MySQL Metal offering. Their architecture uses real Postgres with a proprietary operator (likely Kubernetes), local NVMe SSDs for performance, and a custom proxy called PS Bouncer for connection pooling. Benchmarks show PlanetScale outperforming Aurora, AlloyDB, Neon, Supabase, and others primarily due to local NVMe vs. network-attached storage. Additional topics covered include: why UUID v4 primary keys hurt performance and why UUID v7 or integers are preferred, how PG Search built replication-safe LSM trees in Postgres, using raw SQL in Go instead of an ORM, Postgres as an analytics pipeline data source, and the Percona pg_tde transparent data encryption extension reaching production readiness with a performance impact of up to 20% slower on write-heavy workloads.
