Pros & cons
TiDB
- MySQL compatibility with horizontal scale
- Strong for large distributed SQL workloads
- Open-source plus managed TiDB Cloud
- Heavier than single-node MySQL/Postgres
- Ops learning curve for distributed SQL
- Not the simplest hobby database
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
