When creating a PlanetScale Postgres cluster, you can choose from any of the Postgres versions we support.
PlanetScale Postgres supports versions 17 and 18 of Postgres.Specifically, the following versions are currently supported:
17.5
18.1
New databases will be created using the latest version by default and we recommend sticking to that default, but you can choose an older version if you need to.
PlanetScale doesn’t currently offer in-place upgrades between major versions of Postgres. To upgrade from Postgres 17 to 18, create a new PostgreSQL 18 database and perform an online migration from your existing PlanetScale Postgres 17 database using our import guides.
