Pros & cons

PostgreSQL

  • Gold-standard open-source SQL engine
  • Huge extension ecosystem (including vectors)
  • Foundation for many modern BaaS platforms
  • You assemble auth/storage yourself
  • Ops complexity grows without a managed host
  • Not a serverless product by itself

MySQL

  • Ubiquitous skills and tooling ecosystem
  • Battle-tested for OLTP web workloads
  • Easy to self-host or buy managed MySQL
  • Not Postgres-compatible
  • Fewer modern branching/serverless DX features than Neon-class hosts
  • Advanced features often need careful ops
